Install sunshine/moonlight on a PC and deck pair, and you should be able to play Epic Games from the heroic launcher. I didn’t get much into it at the time, but you can shortcut games in the moonlight client so everything starts when it’s selected. Without setup, you can already stream desktop mode, open Heroic and start there.
I don’t use the deck, but I do stream to a micro Linux box connected to my TV and an Xbox controller.
They probably don’t want to make Heroic the official way to play Fortnite on the Steam Deck either.
