Expension Pass not transfered to Steam after the game move

I purchased Glaciv IV, the expansion pass, and Supernova upgrade on Epic. I just used the Steam key transfer service. On Steam, I dont see any of the  expansion pack in my account.

Was this what was intended with the transfer?

At the price of the expansion pass I was hoping it would have transfered.

Making a ticket was useless, just got automated responce to go in the forums... so here we are.
