WiVRn is so stupid easy to use. You just copy the launch command from the app into the Steam launch options and hit run. It just works. Other than occasional hiccups, it's the most stable and simple VR application for Linux I've used.

There is also a companion app that doesn't require installing outside the Meta Quest store (although loading via APK is an option). The headset app lets you launch games directly from the headset.

SteamVR also works fine if you're on Wayland and KDE. There is a SteamVR app for Quest and other Android-based headsets that works with the native SteamVR application.
