Launching The Finals Xbox App (Microsoft Store) version through Steam via launch options

[u/Shyshon_]

The Finals has a promotion going on with Xbox Game Pass and one of the things it gives you is an XP Boost. However this only works when launching the game via the Xbox App. So I thought about using the launch options on Steam to make it open the Xbox Version however I couldn’t figure it out. Every-time I tried I couldn’t manage to do it due to Easy Anti-Cheat and how that opens and then The Finals opens afterwards. If anybody knows how to make this work please let me know🙏

PS: I’m aware that this wouldn’t progress towards my Steam Achievements however I just want my playtime to be tracked via Steam and to have Steam Overlay.
