We are trying to implement Lightning Knowledge in our cases. We want our tech support team to insert articles into an email in the feed email section of the case. However the only way to let the Tech Support users do the inline attaching is to give them the View Setup and Configuration Permission, View the App Setup and Administrative Settings page. 

Why do we have to give our users access to setup in order to allow them to insert an article into an email from a case.
