Hello team,
We have 4 service desk projects under one instance, for different partners. And we have a need to separate users from each portal.
Difficulty #1. We do not want to restrict customers from raising a request without being logged in (using a widget) and use the portal they are registered at (is this possible at all?)
Difficulty #2. There is no "Customers who have an account on this Jira site" in my Customer Permissions tab

Please advise.
King regards,
Val
