Group Role Member

We are trying to do a couple of actions after a user joined the group. we are using GroupUser.AfterCreate event in the automation and it's working fine if a member joins the group directly.

But the same case is failing if the user is added by a role membership. The automation doesn't trigger at all.

What would be the event that would fire after a member is added to the group by role membership?

Thanks
