@kelpana Thanks! Yeah I wish it was available also on earlier headsets, I have a Quest 1 myself and it's now a brick after just a few years.
My understanding is that it relies on OS features that are pretty cutting edge and not available in earlier devices.
But maybe with time the contributors will find an alternative way to make some of it work on Quest 2. At least a few years back the "normal" flat Android editor "worked" when sideloaded on Quest 1 IIRC, but was mostly a gimmick.
