Unable to add customers for portal access invite to JSM as "service desk agent " & as Project admin & Jira admin,
This is for users that already have a Jira account on cloud site. just was to send them an invite to the helpcentre portal.
keep getting this messaged checked everywhere, i have all the correct permission on the project and global,

checked https://confluence.atlassian.com/servicedeskcloud/resolving-jira-service-desk-permission-errors-1097175958.html
sections "Granting permissions to this role gives customers access to Jira functions. Customers should only have access to a Customer Portal and permissions should be granted to the Service Desk Customer - Portal Access security type.
As a result, administrators will not be able to add any customers to the service project. Open service projects will become restricted. Public signup will be disabled."
still the same error appears, although the site admin can add customer.
Thank you in advance for the help,
