Private Marketplace content restrictions

All, This is regarding private Marketplace content restrictions. We have bunch of modules and we want to restrict access/download these modules to certain groups in the company. Based on Mendix document below, it says we can create group and assign the content to manage but it doesn’t explain how to restrict download access to specific group. Please help.
