i am wondering how to add such a gamepass game to fanalab since these games don´t offer any *.exe file to add to a game profile. I want fanalab to load the according profile once the game is starting.
It's not possible to add Games from the Microsoft Store to FanaLab because Microsoft is blocking access to those exe files
To be clear, you can still add the games from Game Pass if you simply want a way to keep all of your profiles properly organized by game. You just can't launch them from within Fanalab.
For example I have Wreckfest on Game Pass, and have added it to Fanalab with its own picture, but when Fanalab asks for the exe, I simply point it to some other game or application. I just have to make sure that I then manually load the profile I want before playing. But I always do this anyway, so for me it's not a problem.
