DLive.TV solve invisible recaptcha

#1
Hi all.

I am building a signup bot for dlive.tv on C# and Selenium.

I am using 2captcha.com API for solving captcha. I think this site using invisible recaptcha v2.

On the signup process, a captcha presenting after the click "SIGN UP" button.

I am getting the token from 2captcha API.

Where I can paste this token or how I use callback functions?

Sorry, I am a newbie in programming.
