Further comments

Todo's (Possible Engineering day items):

• Migrate "UnitEdit" component on UI to use endpoint instead of "livechat:saveUnit" meteor method
• Create a new model for "LivechatUnitMonitors" with updated types
  • remove unwanted field "monitor.username" (since we're already storing userId)
