How to sync save from GOG?

I've installed Control Ultimate Edition from my GOG account through the Heroic Launcher in my Steam Deck. I already have 3h of gameplay in this account. However, when I start the game I don't get any option to continue from a save, only to create a new one.

Did I miss something? Do I need to configure the sync details? I didn't find anything regarding that.

Any help would be appreciated.
