I've added a reCAPTCHA to an external Hubspot form but when I submit the form I get the image challenge to solve. From my understanding from Hubspot the reCAPTCHA requires zero user-input https://www.hubspot.com/product-updates/now-live-googles-invisible-recaptcha-available-on-all-hubspot-forms .
Maybe I've missed a step somewhere? Or maybe something needs to be added to the embeded code.? This is where the form is located https://www.esabna.com/us/en/dmx/index.cfm
