Since 1.3.0, CAPTCHA challenge is triggered on form focus by default. The challenge is automatically refreshed every 2 minutes. This should be compatible with most extensions. If, for some reason, this doesn't work and you're getting Captcha answer is missing errors, the behavior can be changed using Trigger Method setting. On Page Load option is the most compatible with extensions but also triggers the challenge on every page load where CAPTCHA is displayed. This is not recommended for performance reasons and may exhaust your reCAPTCHA tokens. The challenge is also refreshed every 2 minutes. On Form Submit option triggers the challenge only when user submits the form. This is the most conservative option but is also incompatible with some extensions.
