 *
 * Instructions:
 *  1. Add snippet to form using https://gravitywiz.com/gravity-forms-code-chest/
 *  2. Customize inputButton and optionally buttonSelector to match your form the desired field
 *  3. Add HTML field to your form and add the following code to the HTML field:
 *      <button class="trigger-gppa">Click Me</button>
