Here are steps on adding CAPTCHA/Re-CAPTCHA to a webform (like the Contact Us form):
- Navigate to the webform and inspect a field (right click any field on the webform → Inspect)
- Find the hidden component with the name of "form_id" and copy the value name
3. Add that value as a new form ID: /admin/config/captcha (Coffee: CAPTCHA)
4. Configure to RECAPTCHA
5. Save - CAPTCHA should now appear on the webform!
