Possible values for user-type tag in PRIVMSG

Chat and IRC
#1

The reference says

user-type The type of user. Possible values are:

  • “” — A normal user
  • admin — A Twitch administrator
  • global_mod — A global moderator
  • staff — A Twitch employee

However, I know one value for user-type which is not mentioned here at least: user-type=mod for channel moderators.
Is there more accurate list for possible values of user-type?

global_mod is no longer a thing that program is long dead.
mod is likely the only one missing.

Most people use badges to determine role instead of this tag
