About Flatpak

If you use Flatpak OBS, you need to install Flatpak OBS plugin.
If you use Flatpak Steam, you need to install Flatpak Capture tools to be able to capture games running inside Flatpak Steam runtine.

For capturing games outside Flatpak runtime, you need native build regardless of if you are using Flatpak OBS or not.
