Linux Gaming

I'm currently using Bazzite Gnome with open Nvidia drivers, and I cannot get Steam Input to work with non-steam games at all. I have games from GOG and Epic Games that I downloaded through Heroic Games Launcher, and I tried everything for steam input work with them, but it just doesn't seem to work. Here is what I did:

1. I added the games to the steam client.
2. I configured the device inputs under "Controller" from the settings menu.
3. I made sure that the game I want to play has steam input turned on.
4. I disabled the "use desktop configuration in launcher" option.
5. I disabled steam input for non-game controller layouts.
6. I made sure to enable steam input for all types of controllers.

Non of these steps seem to remedy the issue. I want to make it clear that I did not experience this issue while using the Steam Deck, which is also running a Linux distribution. Any suggestions?

Thank you in advance.
