Atlassian Permissions for connecting custom email

[Dort IS]

We are currently trying to set up a custom email address for one of our projects in service management, but every time we do it gives us this:

"Need admin approval

atlassian.com

needs permission to access resources in your organization that only an admin can grant. Please ask an admin to grant permission to this app before you can use it."

Our network admin added the Atlassian Cloud app to our Azura and gave it the 5 most common permissions but it is still not working. What permissions does it need to allow this to work?

You must be a Jira site admin to add a custom email account.
