What permissions do I need?
To access the Alerts overview area and delete alerts, you need the Triggered alerts (manage) permission (see a detailed description of the alerts permissions here).
Deleting triggered alerts
You can completely remove a triggered alert from the list when you no longer want to keep record of it, or you can also delete several alerts at the same time.
Deleting a single alert
To remove a single alert entry from the record, simply click the ellipsis menu at the end of the row and select Delete.
Deleting alerts in bulk
Check the boxes next to the names, click the Bulk actions button next to the master checkbox, and select Delete.
