Example:

BLOCK:PuppeteerOpenBrowser
ENDBLOCK

BLOCK:PuppeteerNavigateTo
  url = "https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox.php"
ENDBLOCK

BLOCK:SolveRecaptchaV2
  siteKey = "6LfW6wATAAAAAHLqO2pb8bDBahxlMxNdo9g947u9"
  siteUrl = "https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox.php"
  => VAR @SOLUTION
ENDBLOCK

BLOCK:PuppeteerExecuteJs
  expression = $"document.getElementById('g-recaptcha-response').innerHTML = '<SOLUTION>';"
  => VAR @puppeteerExecuteJsOutput
ENDBLOCK

BLOCK:PuppeteerSubmit
  findBy = Selector
  identifier = "form"
ENDBLOCK

Note: The Submit block only works with form elements. If you want to target a button element, then please use the Click block.

Validation
Sometimes the reCaptcha must trigger a validation function after you inserted it inside the textarea.
You can easily see if that is the case by looking at the div using inspect element. For example on the reCaptcha demo site you can see this:

<div id="recaptcha-demo"
  class="g-recaptcha"
  data-sitekey="6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-"
  data-callback="onSuccess">
</div>

The onSuccess function is the callback function when the challenge is solved.
In this case you just need to add onSuccess(); to your script and it will look like this:

document.getElementById('g-recaptcha-response').innerHTML = '<SOLUTION>'; onSuccess();

More info about callbacks can be found at this page.
