How to call callback hCaptcha on a website?

Question

CAPTCHA

Hello! Can you tell me how to call the hCaptcha callback function on the site? Or how to pass a token to it? With reCaptcha, it was enough to call the callback via ___grecaptcha_cfg, passing the token. But with hCaptcha, I can’t find any information anywhere. I would be very grateful for help in this matter.

There is no PS form on the site.
