Update (08/2020): Some things changed since I firstly wrote this, so here is the revamped version. For more detailed info, view Microsoft's article About IE mode
So, since it took me almost a day to collect all necessary info and successfully set up IE Mode in Edge, I thought it may be helpful to post a step-by-step manual and some useful notes.
1. The flags aren't there anymore in current Edge Stable, Dev and Canary, so you can skip this one.
To activate IE Mode open Edge Dev and go to experimental features by typing edge://flags/ (Note: Edge Canary doesn't support IE Mode by now)
2. If you don't have an Enterprise Mode site list download the Enterprise Mode Site List Manger v2 from https://www.microsoft.com/en-us/download/details.aspx?id=49974
(Note: the site list xml has to use the v2 scheme to work with Edge Chromium)
3. Download the Edge Chromium group policy template files from https://www.microsoftedgeinsider.com/de-de/enterprise
4. Open the Local Group Policy Editor and edit the following entries in Computer Configuration > Administrative Templates:
Optional, but not needed for IE Mode: For compatibility, you can set the following, so Enterprise sites visited in Classic Edge will open in Internet Explorer.
The 4 policies above can be also set via registry:
Force update of the policies to take effect immediately by either running gpupdate /force on an elevated prompt or rebooting your machine.
To check if Edge is recognizing your sitelist correctly, type edge://compat in the address bar. This will show all entries from your XML-sitelist.
More diagnostics for IE mode can be viewed in edge://compat/iediagnostic
This worked for me on different machines using Windows 8.1 (Pro and non-pro) and Windows 10 (1909, 1903, 1809) with Edge Stable, Dev and Canary.
Please get back to me if I missed something so I can update the manual.

The only missed step would be a system restart/reboot after all the Registry changes are completed. At least that was what I needed to do before Edgeium took the changes.
Here is the Microsoft URL documenting the steps using IE Mode for Edge Enterprise.

So to enable IE mode you need to configure group policies under Administrative Templates > Windows Components > Microsoft Edge > Use the Enterprise Mode IE website list > Configure Internet explorer Integration and under Administrative Templates > Windows Components > Microsoft Edge > Use the Enterprise Mode IE website list
Will the GPO for Edge chromium be split into these two location in the final release ?

I'm pretty sure it will, because
But I'm not a developer, so please don't quote me on that.
Btw., the "Use the Enterprise Mode IE website list" policy in the Classic Edge GPOs is not needed for IE Mode to work on Edge Chromium Dev and Beta. I just added it in the manual for compatibility issues, so that Enterprise sites visited in Edge Classic will open in IE (I've updated the manual to work this out).

@Neon01 Thank you so much sir to share this great information.
I am using Windows 10 Home Edition 64 Bit, since group policy related settings are not available in Home Edition, so in step 2, I added more than one website and skipped step 3 and 4, directly go to registry editior(regedit) method and opened directory:
1. Created new key Edge, so it would be
created new DWORD without any mistake InternetExplorerIntegrationLevel and set it's value to 1
2. Again go to following directory
Just create another following keys under Microsoft
and close registry editor, sign-out and again sign-in PC, then internet explorer mode will work for all sites.

I tried your way and mine didn't do anything.

I have MS Edge Version 84.0.522.61 (Official build) (64-bit) on Windows 10 build 1809 (17763.1339)
I tried to follow your steps to enable IE integration and was not able to find this from step 4.
Enable Microsoft Edge > Configure Internet Explorer configuration and set it to Internet Explorer mode
Here is what I see:
If I go to Windows Components, I see Microsoft Edge, but no Configure Internet Explorer Configuration:
Also in the registry I don't see HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge >
and HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge >
Should I just create them manually?

if you can't see the the Edge policies in the MMC (Microsoft Management Console) policy manager, either you didn't implement the policy files correctly or you copied them while the MMC was open. This is a known bug, if you copy new policy files while MMC is opened, they won't be recognized.
Anyway, just create the registry entries manually, that's what the policy does too.
Btw, what you found under "Windows Components" are the policy settings for classic Edge (Edge HTML).

I verified that I have msedge.adml in C:\Windows\PolicyDefinitions and msedge.adml, msedgeupdate.adml in C:\Windows\PolicyDefinitions\en-US. Restarted gpedit and still could see not see MSEdge under Computer Configuration=>Administrative Templates.
Should I reboot my machine for it to work?
My machine is on the company domain and it is possible that some GPOs causing this.
I'll try to add to the registry directly, if still not there after reboot.
Thank you for a quick response.

I added Reg keys and rebooted machine an everything working now.
