Reporter is not receiving email notification when agent adds a public comment
Problem
As a service desk agent, I add public comment on a request, and the reporter is not receiving emails
Solution
This a configuration that can be modified on your environment by changing the settings in Service Desk project.
Open the project and then Project Settings and then click on Customer Notification
Click on Edit next to Public comment added
Make sure to add reporter to the top dropdown (To)
This would be important if you choose creation behavior
Creator & Participant = PUBLIC_USER | Reporter = EMAIL_ADDRESS
