2. Add a user that has a JSM license but is not a site administrator nor do they have the global Administer Jira permission
3. Navigate to Service project settings > Customer notifications

Workaround

While not ideal, granting this user Administer Jira permissions via Settings > System > Global permissions will allow them to interact with the page.

Side note

The documentation found at Edit a team-managed customer notification mentions You must be an admin to edit a customer notification however I do not believe this refers to global Jira Admin.
