Currently, notifications are hard to troubleshoot. If the script has an error, it will show that error in the exclamation mark. However, it is not possible to fix the script and verify that it works now.

Therefor it would be nice if a "retry' button could be added in case the notification failed. When clicked, it should retry the notification again with the same input. This would allow for easier troubleshooting by making modifications to the Media Type and immediately testing this with real-world data.
