Jira Automation - Actor for manual trigger

I would like to assign the "User who triggered" actor to an automation rule with a manual trigger.

A user has created some rules which have a manuel trigger however when the rules are run, the history shows the actions were done by user who created the rule (the original actor).    For auditing purposes, this is not ideal.  The desired outcome is for the issue's history to reflect the user who ran the rule, as opposed the owner of the rule.   I also, for the same reason, do not wish to grant them the impersonation permission.

I experimented by creating a rule as a jira administrator to see if it would make a difference, I also granted the impersonation permission before re-creating the rule, however in al those instances I never had the ability to set the "user who triggered" actor, at best i can pick a specific user but I cannot make it dynamic so that the user who runs the rule becomes the user who is seen doing the action in the issue's history.  

Any guidance would be appreciated.  Thank you.
