30_os-prober

Does it make a difference if it is called 30_os-prober_proxy?

if zorin or bazzite still don't show , there's further steps then

Zorin shows in the konsole, Bazzite doesn't.

I have no idea what the "_proxy" version is about. I use Kubuntu and KDEneon and that entry does not exist for us. You should probably ask in a Zorin or Bazzite forum.
