On case, I have 2 lookup fields on case: Contact and Case_Contact__c
The contact will always be the person who is creating case. The case contact can be any contact selected by customer.
Once a case is created, we are changing the owner to queue.
I have created a sharing set to assign the access to contact based on current user login. How I can give access to the other user whose contact is present in Case_Contact__c field of case?
We are using customer community license (Not plus one).
