How To Map Some Docs to Some Particular Group and Roles

Hi Guys,

I am using the Mayan EDMS Open Source application and can create everything like Users, Roles, Permissions, and Groups, and upload documents. However, I am not able to establish the relationship between documents and users (Roles, Groups). Please help with this section if anyone is aware of how to do this.

This means I want to permit some docs for some groups or roles.
