Pabbly Integration Improvements

Pabbly is missing some triggers & actions that are much needed to be able to fully migrate away from Zapier.
I'm pulling these over from this completed feature request:
https://heartbeat.canny.io/feature-requests/p/pabbly-integration
TRIGGERS NEEDED:

• On Group Join
• New Thread
• Course Completed
• Updated User (currently we only have "new or updated user" and "new user"
• I believe it could also use some event triggers
  ACTIONS NEEDED:
• Create New User
• Update Users Info
