VK captcha bypass, sending a POST request to go through Google Recaptcha?

Question

JavaScript

Hello.
I'm trying to bypass captcha in VK using recognition services.
I get a hash answer to the captcha, send it to the response field.
After that, as they explained to me, it is required to send a POST request, identical to what is sent when passing the captcha.
POST request is required because VK captcha does not have the ability to send it with a button, it needs to be solved, and if the solution is correct, then VK will close the captcha window itself.
I am attaching a screenshot of the POST request that was sent during the normal captcha solving.
As I understand it, the request must be sent from the same window, that is, through the browser console and to JS.
Therefore, I beg you to help me compose this request, I tried - I often get a similar answer:

No 'Access-Control-Allow-Origin' header is present on the requested resource.

I will be very grateful for the made request on JS or C#.
