I'm trying to locate the callback function name used in recaptcha v2 but I have little experience in javascript so I don't understand the source code. I'm using 2captcha.com as the captcha solver service and I'm using this guide https://2captcha.com/2captcha-api#callback I'm unable to identify the callback function name since it varies on each refresh. So far these are the working callback function names I found just by guessing
Code:
___grecaptcha_cfg.clients[0].aa.l.callback
___grecaptcha_cfg.clients[1].aa.l.callback
___grecaptcha_cfg.clients[2].aa.l.callback
___grecaptcha_cfg.clients[0].ba.l.callback
___grecaptcha_cfg.clients[1].ba.l.callback
___grecaptcha_cfg.clients[2].ba.l.callback

Can anyone help me read the source code and identify all the callback function name used for solving recaptcha v2? source script is here https://pastebin.com/8nptzQY3
