We have multiple departments split into multiple groups in one zendesk instance. Agents who are the requester on a ticket are able to see internal notes made by the assignee agent, even if the requester agent is not a member of the group the ticket is assigned to.
For example, someone in IT submits a ticket to someone in Facilities. The member of IT can see any internal notes the agent of Facilities makes on the ticket since the member of IT is also an agent in Zendesk. This is an issue as information meant to be internal only for that department is seen by the requester of the ticket.
