How do you redeem the code?

Where do you redeem the code so that you get the coins.

Because we can't find anything where to enter the code

(Have xbox one)

I have no idea and I just watched a yt video but they say you have to go to store and then click on "use a code" and then you tap on this symbol.

Kind regards Buchling

That's the YT video

PS: the video is in English

Thank you, that worked.
