I only use this program for steam games and then I realised that i could use this for the pc game pass app because i have a ssubscription on my xbox. I am looking to use it on singleplayer games such as State of Decay 2 but i REALLY don’t want to be banned by xbox because i could be tampering with software. Can someone give me clarification?
Welcome to the community. 
The Xbox Game Pass subscription is just Windows Store Games. Windows Store, a very unpopular platform with the wider gaming community, are trying to rebrand as Xbox Game Pass to try and make themselves sound a bit cooler to gamers.
Any trainer designed for Windows Store here on WeMod will work with “Xbox Game Pass” - they’re exactly the same thing.
You’ll only be banned for using trainers if you attempt to use them in online game modes (multiplayer, co-op). 
Thats great news. Thank you for replying.
You’re very welcome. 
Enjoy using WeMod with your games.
