I have a requirement: I need to send a email notification when there is value in co-assignee and whenever status notes got updated.
I have created a workflow like this:

when you click on run if->

and when you click on email notification->

but I have no idea how to trigger only on status notes->so I have triggered on when whole form got modified like below->

Please help me anyone. Thank you in advance.
Thanks,
Haritha.
