[Solved] How do I add it to the form?

I have installed the plugin and pasted in our keys, but now I'm stuck.

How do I remove the default captcha from the form and add the Google Recaptcha to it?

I find nothing in the setting for it, and in the form builder I see no way to remove the default "Code" captcha, and the Google captcha is no available as a field to add to the form.
