Custom WP Admin?

Question

JavaScript

Colleagues, hello!
I have the task of developing a custom admin panel on wordpress.
Someone faced such a task? In what direction to dig and what is the right way for such a task?
A separate role or maybe some kind of plugin is with which you can customize.
Approximately, the following result is needed:

Answer 1

In this case, I see only such an option - to create a new admin panel on top of the usual one. Those. the usual admin panel remains, but there is no direct access to it - it is made for the admin of a special page, to them - an authorization form. All logins/logouts from the account with the help of hooks close to this page.

Answer 2

Rest API solves all problems

Answer 3

There is a plugin that implements all this and even more.
