User permission - Extension

Hello,

We would like to be able to deny access to "Linkus Clients" to certain users.
On the other hand, we find that if we give admin access to a PBX user, he can reactivate the rights.
My question is:
When we give admin access to a user, it would be nice to have the possibility to reduce the rights on the tabs of the extension.

 

For example not being able to access the menus:

Features, Advanced, Security, Linkus clients et Phone.

 

Thanks in advance.

Best regards,
Sebastian.
