how to play dirt 5 via gamepass?

I have xbox gamepass ultimate on my pc and the gamepass catalogue shows dirt but i cant install it. when i asked microsoft support they said it was a listing issue with the ea app. Dirt 5 requires you to connect to the ea app when you try via gamepass but when i opened the ea app i couldnt find dirt 5 on the store??? How do i play Dirt 5??
