I tried this demo (https://www.google.com/recaptcha/api2/demo) in a new incognito window. Then in devtools:

  javascript:if(!window.jQuery||confirm('Overwrite\x20current\x20version?\x20v'+jQuery.fn.jquery))(function(d,s){s=d.createElement('script');s.src='https://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.js';(d.head||d.documentElement).appendChild(s)})(document);
  $('iframe').contents().find('.recaptcha-checkbox-checkmark').click()

I got an extra verification (enter two bits of text)
