How to add recaptcha to newsletter form?

My embedded form is directing subscribers to the hosted version of my Mailchimp Signup form with ReCaptcha request. Mailchimp confirmed to look for required fields that have been hidden on signup form or deleted from the form code.
Can you please help me add ReCaptcha to the form so my subscribers stay on my website.

/* Add your own Mailchimp form style overrides in your site stylesheet or in this style block.
We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. */
