[2023] I own the game on Steam and would like to purchase the Season Pass from the Ubisoft Store and wondered if it will be compatible?

Hello, like the title is saying, i bought ac valhalla with steam and i want to buy the season pass and the dlc key with ubisoft, if i do this can i play the dlc on my ubisoft account with the ac valhalla game that i bought with steam? i mean ac valhalla is in my ubisoft library but only because my steam and ubisoft are linked together, the base game comes from steam, would be nice to know before i pay the dlcs
