Steam Deck

It's generally much better to use HeroicGamesLauncher IMO

Nah, don't support companies that are actively and openly hostile to Linux

I spent hours trying to get Epic to work before saying "fuck it" and pirated the games. You know we're in the worst timeline when pirating is infinitely easier than installing games you've bought.

not worth the effort when Heroic does the job better imo

unless there's a niche scenario in which Heroic won't work

Here’s what works for me: I run Lutris (flatpak), pick up Epic Games on the left panel, proceed with login in Lutris. Once logged in, I pick up a game and hit install. When running for the first time it will install EGS. Proceed with the installation, launch and login in the EGS if it’s first launch. Install the game choosen in Lutris in EGS, then close EGS and Lutris should figure out that the game is now installed. You can test it from there, but you can now add your games to Steam from Lutris by right-clicking them. If adding games from Lutris doesn’t work, it might be problem with Flatpak permissions. I use Flatseal (available on Flathub just like Lutris) to edit them. Lutris must be able to write in ./local/share/Steam and if I remember correctly by default the path was added, but with the :ro flag that I deleted.

Thanks for sharing!
