How do I download a gifted game

My birthday just recently passed, and as a gift, my girlfriend bought me the new Call of Duty: WW2. She at first didnt know if she ordered a physical copy, or bought a digital download. Upon further inspection it appears she bought the digital launch edition.
My problem is I don't know how to download the game onto my system. Did I receive a code I'm not seeing? If she bought it on her account is it only playable/downloadable on her account? If this is the case is there any way to transfer the game to my account?

Thanks for the help

:)

 

How can you determine where gifted points went

If you read my post again you will see i clearly stated the points had NOT been gifted to a family member. Obviously i checked my billing which is how i found about the gifted points. I haven't bought the points and i certainly haven't gifted anyone. I have
phoned support and they are investigating because they do not know where the points were gifted to either as it was not someone in the family plan and they don't have access to download. Therefore I have been hacked.

 

Game gifted via micrsoft store

i am located in UK and have been gifted a dlc code for a new game which was purchased in Brazil. When i try to redeem the code it says it is not compatible with my region, i thought xbox one was not region coded. So how do i download the code?

 

If she bought it on her account, it would be tied to her account. She would either need to set your console as her Home console so you can access the game or she would need to contact support to see about refunding the game so she could purchase the game
under your account. 1-800-4my-xbox if you're in the US/Canada or Contact Us | Xbox Support

 

You're a life saver my friend. I contacted support and got it all figured out. Thank you so much.
