Call Of Duty Cold War on pc

I have a friend that has cold war and we both play on pc. I looked if cold war was in the rewards but it is only available for xbox. I wonder if it would be possible to add blizzard codes for cold war.

Currently G2A or any other retailer that we got the game codes/gift cards from does not have any Blizzard codes for the Rewards.

So this is impossible to do without partnering with ActivisionBlizzard.
