Implement Edge Chromium support in Kiosk mode ("Assigned Access" in Windows 10)

I successfully authorized MS Edge Chromium Stable in a multiapp kiosk mode on Windows 10 1909.

Here is an example of the configuration I used:

<?xml version="1.0" encoding="utf-8" ?>
<AssignedAccessConfiguration

I'm not certain that "%PROGRAMFILES (X86)%\Microsoft\EdgeUpdate\MicrosoftEdgeUpdate.exe" is needed but I think it may be used to update Edge Chromium since it does not update via Windows Update, like the old Edge.

Note that I did try via AppIDs (MSEdge and Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge) but it did not seem to work.

As for the single app Kiosk mode, it should work similarly.
