Firefox screen sharing not working with Microsoft Store Apps

Hello!

I often share my screen in video conferences. It works pretty well except I try to share a window of a Microsoft-Store-app.

The windows of these apps just don't appear in the drop down menu where I can choose the window I want to share. This affects also the Microsoft Store itself and the Windows settings-app.

I have no problem sharing these windows in Google Chrome.

If anybody has an idea how to fix this, I would be very happy! Thanks!

I use Firefox 85.0.2 on Win 10 64 Bit Home on a Dell desktop PC.
