Nevermind. Found out it was a failure on my part. By default it does not show un-installed games. Because I had no games installed, it always showed no games. And I assumed it was broken.
I'm in the same boat. I installed Bazzite oh my desktop as well as on my Legion Go. Everything runs out of the box. Except Lutris.
Maybe he's a trust fund elf from some royal lineage?
