Can I transfer deck/home-city data between platforms?

I started playing AOE3 DE through Microsoft store game pass and made some decks etc. I’ve now bought the game on steam and was wondering if it was possible to transfer my decks over between platforms?
I’ve looked in the game folders for each and they look basically the same but can’t see any specific folder for home city data like in the original. Anyone know where to find it?

Edit: I found the savegame folder by searching “homecity” on installation drive.
