I have never used it. if the official website does not implement it, you can set several restrictions on the displayed page. for example, you can first determine whether it is a specific group (or user). If not, you can jump to the prompt, if no specific group exists, you can put all users that can be accessed in a folder and then judge. of course, this method is also used when dede does not provide
