As a Service Desk administrator, I would like to restrict knowledge bases access to specific customers

Problem Definition

Currently, every customer can have access to any knowledge base linked to a Service Desk project. We can restrict access so that customers can only see Service Desk where they have the Customers role but we cannot do the same for knowledge bases.

Suggested Solution

As a Service Desk administrator, I would like to restrict access to a service desk knowledge base from customers that are not part of this Service Desk.
