Hiding menus for clients

Hello and thanks for this incredible piece of work!

I’m a bit confused with this section Menus > White Label CMS Admin for hiding menus to clients.

In a previous installation where I am the only admin, I read this:

You are now a White Label CMS Admin. This allows you to modify the menus that other people will see.

You: myemail@gmail.com

By selecting a White Label CMS Admin it means that only the selected Admins will be able to modify the settings for White Label CMS, as it won’t be visible in the menu to anybody else.

But if the site has already 2 admins, who is the “selected Admin” and which setting defines that? How do I become a “White Label CMS Admin” when installing the plugin and there are other admins already enabled?

For different reasons, I want to create an Admin role for a client but, at the same time, hide some menus from his view in order to avoid accidents.

Thanks!
