After you click the link yes, it says it's the win version - but after you open the trainer itself, inside it's window in the upper right corner it's written Steam version.
It seems however the Steam text is the only error, because the trainer itself works as intended with the Game Pass version.
Please disregard my previous comment.
If you cand fix that text, please do. But the trainer itself works fine.
Sorry for the fuss.
