Google Invisible Captcha V3

[rupertvz]

Hi Guys,

I am trying to implement Google Invisible Captcha V3.
I got the first part working, including the Java script as part of my form HTML code.
The invisible captcha is showing ;-)

I am now supposed to receive and process the incoming result by means of the following code:

<script>
  grecaptcha.ready(function() {
      grecaptcha.execute('reCAPTCHA_site_key', {action: 'homepage'});
  });
</script>

Where do I put this code in my NWF to load after the form has been submitted?
Currently my form calls the "IndexPage" (URL on Save)
