How to put non-Steam applications on the Steam Deck
Once you’ve downloaded your games fromGood Old Games or the Epic Store,Battle.net, or wherever else you might acquire video games from, enterDesktop modeand open Steam.
In the bottom left corner of the app, there’s a plus sign button and it’ll give you the option to add a non-Steam game to your library.

It’ll open a window for you to search for your games. Ensure you know where you’re looking before heading into this, as Linux isn’t as simple to find files asWindows.
