you should use Linux, then you will see what no support looks like
The ticketing system gives these options
“Linux (not supported)”
“other”
Guess what we pick? yes, “Other” (well it’s true, it’s my own distro and Linux is NOT a distro 
it’s a kernel, and wine/proton is not Linux is it, it’s “other”, and there is no native Linux client anyway, even though QT is cross platform).
“Other” is apparently supported (it doesn’t say “not supported”)
