Add "Close list" (Or etc name) in the servers a list of people in the role (Which in the settings in the roles that includes "Display role members separately from online members")

I don’t know yet how I can tell you more... But I will tell you a few works. In the list of people in the role will be an invisible button with the text "Close list"! When you click on this button, the list of people disappears and the name of the role is simply written and the "Close list" button changes to the text "Open list". If you click on the modified "Open List" button, the text "Close List" will return and the Members of this role will be visible!
