Game sharing.

I 'own' this game because a friend is game sharing it to me through Xbox. Is there a way to download this game shared game onto my pc? Viewing it in the store says I have to buy it. (Yes I'm signed into the same Microsoft account) (It is playable on Xbox and I'm quite thankful, but I would like it on pc aswell) . And yes I've tried searching around the Xbox app and things like that. Any help would be appreciated. Thanks!
