Some very obvious mistakes:

1.  You didn't show before that "/path/to/AppleVNCServer" included
AppleVNCServer.bundle, that derails this train (i.e. the name appears
twice), I would change:

SSHD_FORMAT_REGEX=.*(sshd.*:|\[sshd\]|AppleVNCServer\[\d+\]:)
(?P<message>.*)

2.  You add .* in a place where it doesn't belong, plus my using
(?P<user>.*) is also not good, I should have written (?P<user>\S+)

3.  I should have asked this before: did you also change your
configuration to monitor secure.log?

I could send you a screenshot of how testing the regex (with Kodos) and
you log works.  Of course that doesn't prove that DH will work since
both regexes have to work.
