I've added customers through the Customers in the left pane. When they raised a ticket on our Support Portal they've been automatically added as a user in the User Management which consumes 1 agent space from our license.
Aside from they've been added as user, they are also added on the 3 groups (users, developers and administrators)
I would like to know if this is how really JIRA Service Desk work? or I just need to change something in the configuration. We thought Agents are the Support team and customers can raise requests/issues without consuming an agent license.
