How can I submit Hcaptcha without a confirmation button. (2Captcha/Dbc)

#1
I using an API to break HCaptcha perhaps I don't know how can I submit it.

In Recaptcha I just need to call the callback function and insert the token ___grecaptcha_cfg.clients[0].L.L.callback("TOKENCAPTCHA"), but in HCaptcha I don't see that.

What I've tried:
Code:
document.getElementsByName('h-captcha-response')[0].innerHTML = '{token}';
document.getElementsByName('g-recaptcha-response')[0].innerHTML = '{token}';
