[Wayland] PWAs no longer appear as separate app windows — all group under main Edge icon

Ran into this same issue while trying to create apps for Teams and Outlook on Ubuntu 24.04. Thank you to the earlier comments about how to resolve this! There was some data missing so here are the steps I followed in case anyone else runs into this later. It's a shame Chromium/Chrome/Brave work but Edge somehow broke this and Microsoft either hasn't noticed or doesn't care.

1. Install your sites as apps.
2. Go to edge://apps and click on "Details" for each app.
   1. In the URL for each app detail, take note of the long string. This is your app ID. In my case, the URL for Outlook was "edge://apps/details/outlook.office.com/faowiofnngnfdaknnbpskhgogbobgeg".
      1. "faowiofnngnfdaknnbpskhgogbobgeg" is what you need to note.
3. Once you have the app IDs, open your Files app and navigate to "~/.local/share/applications".
4. You should see .desktop files for each app you made. The string in the filename should match the string you recorded in step 2.1.
5. Open one of your apps. Press ALT + F2 and type in "lg". This will open a Looking Glass menu. Click on the "Windows" button and find your app. Look for the line below the app name. It should start with "wmclass: msedge<some value here>"
   1. Take note of the structure of this string. You shouldn't need to record the entire string, but pay attention to the structure.
      1. In my case, the string looked like this: "wmclass: msedge-_faowiofnngnfdaknnbpskhgogbobgeg-Default"
6. Close Looking Glass (press escape). Open the .desktop file that matches your string.
   1. Look for the line that starts with "StartupWMClass=<something here>"
   2. Replace the data after the "=" to match the structure of the string in Looking Glass.
      1. My line looked like this after: "StartupWMClass=msedge-_faowiofnngnfdaknnbpskhgogbobgeg-Default"
7. Save your file and close it. Repeat this process for any other apps you installed.
8. Log out and back in. Open your apps. They should now open under their own icons in your dock.

Hope this helps! I made this to help save someone's time. If you encounter any issues with my guide, please share and I'll fix it!
