Fullscreen js and popup authorization

Question

JavaScript

There was a problem. I am making an application on js, I use fullscreen functions in it, there is also authorization (fb, vk).
When the user enters full-screen mode and clicks "log in", the browser exits this mode. Maybe you can do something so that the popup is shown to the user without leaving the mode. This happens on mac os.

Answer 1

It is forbidden. I don't even know what arguments to give.

Answer 2

You can try to show the authorization window not in a separate popup, but in a positioned iframe inside the page.
