On Mac OS 12.3 Any advice on how this works now? I get the following errors and I am able to login but get a black screen.

Trying to read up on this MDM configuration stuff but sounds relatively new and I'm not a Mac person so I'm not very familiar with how to manage these machines from a fully remote setting.

Screen recording might be disabled. Screen Sharing or Remote Management must be enabled from System Preferences or via MDM.

Similar issue. Not a Mac user and would definitely appreciate any suggestion to enable the built-in VNC server via terminal.

Here is a script to set VNC password in macos 10.14 and later:
echo runnerrdp | perl -we 'BEGIN { @k = unpack "C*", pack "H*", "1734516E8BA8C5E2FF1C39567390ADCA"}; $_ = <>; chomp; s/^(.{8}).*/$1/; @p = unpack "C*", $_; foreach (@k) { printf "%02X", $_ ^ (shift @p || 0) }; print "\n"' | sudo tee /Library/Preferences/com.apple.VNCSettings.txt
