There is no UFC in cloud gaming from Xbox

I adore your company, all games are made by high professionals, you make exciting games. I'm a big fan of the UFC game series, this game evokes a whole range of emotions in me. Of course there are more positive moments, but she still remains in my heart, I have a problem, it’s not available in cloud gaming from xbox, I’m talking about the website. Almost all of your games have been added to the library, why are you avoiding this wonderful game?
