Yeah but the thing is I bought a physical gift card and the funds are already on my account

The Xbox console version, not the PC version

If you look you won't see PC listed as being compatible, and if you do a search in the Windows store app you won't find it for PC

I suggest you initiate a refund and then buy it on a supported platform
