Cloud Saves from Xbox Game Pass to XBPlay (Steam Deck)

This stuff isn’t really my forte, so bear with me!

I’m currently playing Kingdom Come Deliverance on Xbox and occasionally via Remote Play on the Steam Deck.

My husband started playing it on the Xbox as well.

I’m trying to figure out if I can somehow utilize Cloud Saves to be able to play on the Deck while my husband plays on the Xbox.

This is the first time we’re both playing an owned game, as opposed to a Game Pass release (which seemed to automatically work with the “Cloud Play” option on the deck)

Appreciate any insight into whether this is an option or I’m way off the mark.

TIA!
