How to make authorization through APIOK without a redirect?

Question

Classmates

I use server authorization with a line like
https://connect.ok.ru/oauth/authorize?client_id={c...
I want to authorize the user without reloading and redirecting the current page. I decided to trick myself with the help of a div with a nested IFRAME and made redirects inside the iframe. And I got the result:
Refused to display ' https://connect.ok.ru/oauth/authorize?client_id={c... ' in a frame because it set 'X-Frame-Options' to 'deny'
Clearly, classmates forbid for security reasons to use authorization inside the frame.
Any idea how to log in without redirecting the current page?

Thanks everyone! Decided via window.open()
