Not able to play anymore.

Hello, a fellow gamer here. I got hooked with horizon 2, and I would really like to play it again. Unfortunately, the way I got it, (Xbox Live Gold) has expired. I am in “Family” setup, and my guardian has Xbox game pass ultimate on the xbox. Unfortunately, it still says that I need an Xbox live gold to run the game. My guardian has the game, and can play it on their account, but I would like to play it on my account. Is there something I can do to make it work?
