Pre-ordered game to be given as a gift

Hi all,

First, apologies if this should be posted elsewhere.

I dont use xbox so I may be missing something very simple, I pre-ordered FC27 as a gift for my nephew. When I ordered it I created an account (I assumed as per any other website) and I'm currently assuming on the release date I will be sent a code they can enter to get the game on their xbox? Anybody know if this is how it works or how does it work (e.g. do I need to cancel it as I've bought it for my non-existant xbox and order it while in their account)?

Thank you all
