Automations - reacting to bot PR comments

I am interested in setting up an automation which watches for comments on PRs on one of my repos and is triggered when a comment is posted by a code review bot (e.g. CodeRabbit or Greptile). I can’t seem to get the automation to trigger; is there some limitation to the “PR commented” trigger which limits it to comments from non-bot users? I don’t really have a way to view potentially-triggering events and why they did or did not trigger an automation.
