How to get Xbox Games to Steam Library

[Schmaahn]

Hi

I recently switched from Win10 to Win11.
Problem is to get my Gamepass Games to Steam.
UWPhook worked fine on Win 10. Now I get error message "Trying to find installed apps..."
No help in sight (reddit or homepage)

Is there another way to integrate an Xbox game to my library ( also showing playing while I play it)?

I already tried the "add as a non steam game" option and threw administrator-rights left and right.
Now I can open the Windows-Apps-Folder, but steam still denies me to link the exe-file...
