Well according to the information on the trainer information page it is made for the Steam version of the game. I would suggest that if already have the gamepass version that you just try and see if it works.
As they stated earlier, this was a quick trainer, expect more options once they've got a bit more time with the game
goddamnit, I JUST POSTED that we were working on more options. ****ing game has been out like 6 hours. Give us ****ing time to working on the goddamn thing, jesus ****ing christ.
