Do OFME games work on Linux?

I tried playing games that require Steam's multiplayer services on Bazzite using both Proton and Proton GE, but couldn't get any of my friends to join me, nor could I join my friends because the game apparently couldn't contact Steam's relay services. The overlay didn't even show up. The games ran just fine though. The games I tried were RV There Yet? and Lethal Company.
