How do I add my Windows Store version to Steam?

Hi guys!
Im trying to get on the PUP server to try the new Civs, I read that you have to do this on Steam.
But I cant get my Windows Store version on Steam. Can someone help me with this?

Thanks! :slight_smile:

Hi @KimJongOK4904, Unfortunately there is no way to redeem your Microsoft Store license for a license on Steam.
