Hi,
As a Service Desk Agent we often need to forward/share tickets onto 3rd parties.
These 3rd parties have been setup as Service Desk Customers in our Project.
The Requester is another Service Desk Customer.
When we 'Share' the Issue with the 3rd party via the share button on the top-right of the Issue screen in Jira Service Desk, It sends the 3rd party an email with a link and when they click on it they get the below message saying they can't view it.


Questions:
1. Anyone know why the Customer cannot see the Issue? Do they have to be a licensed User?
2. How can we 'assign' or share an Issue with an unlicensed User that they did not create, and for them to have the ability to respond add comments to the issue?
