If you want to play with PC UI, you’ll need to get the PC version of the game, which means it’s not on GamePass (but is available almost always on a super heavy sale).
Then again, the talk about Crossplay is that it will involve Crossprog, which implies you will eventually be able to take your XB account to play on a PC install.
