<h3>External services</h3>
This plugin uses Google reCAPTCHA to protect the WooCommerce product review submission form from spam and automated bots.
It connects to the Google reCAPTCHA service in two ways: 
1. Frontend Integration: It loads the reCAPTCHA JavaScript API from <code>https://www.google.com/recaptcha/api.js</code> on the product page to display the captcha challenge. 
2. Server-Side Verification: When a user submits a review, the plugin sends the reCAPTCHA response token to Google’s verification endpoint (<code>https://www.google.com/recaptcha/api/siteverify</code>) along with the Secret Key and the user’s IP address to confirm the validity of the captcha challenge. This data is sent only upon review submission.
