Send a private message when user has been unblocked (rules intergation)

Problem/Motivation

Posted similar on rules issues yesterday with no reply yet
I have a rule on Drupal 7 who send a private message ( privatemsg module) from the "Content Editor" unique user, quite simple rule
get Entity by ID -> User ID of the Content Editor and Send a message from the user triggered by "User has been unblocked" event

Cannot seem to be able to reproduce it in Drupal 10.
"Send a message" is not available in Rules Action and no "User has been unblocked" available in Events
Every search I did including Reddit, slack etc - no useful results.
What am i missing here on such a simple and useful action?
Thx
