Linking Account PS5 and PC (Steam/Epic)

Hello,

I bought access for PS5 and wanted to also Play on my PC with it, I heard that should be possible.

Unfortunately when I try to login via Steam or Epic it says, that I do not have access to POE2 and yes the Secondary Login under "Manage Account" is also connected, I even used a Key for PC which I additionally bought, because otherwise I could not download the Game from the Steam or Epic Store.

How can I make it work on my PC?

Thanks in advance!
