Console vs PC characters?

I just purchased and downloaded the PC version of PoE2 through steam. I already have it on Xbox but I travel a lot for work so was going to add to my PC. However I don't see how to log in and get access to my characters from my xbox version?? Are they separate?

I don't use steam that often so I wasn't sure the best way to go about it but I'd like to get my Xbox linked acct playable on PC.

any thoughts or did I just do something wrong?
