Message did not send

Hi I managed to Figure it out. When you do the setup via your plugin it seems to skip a step. So when I did connect messenger via the Facebook page I went through all the steps like on your plugin but the last page showed I need to add the Java Snipped.

<!-- Load Facebook SDK for JavaScript -->
      <div id="fb-root"></div>
      <script>
        window.fbAsyncInit = function() {
          FB.init({
            xfbml            : true,
            version          : 'v9.0'
          });
        };

        (function(d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) return;
        js = d.createElement(s); js.id = id;
        js.src = 'https://connect.facebook.net/en_US/sdk/xfbml.customerchat.js';
        fjs.parentNode.insertBefore(js, fjs);
      }(document, 'script', 'facebook-jssdk'));</script>

      <!-- Your Chat Plugin code -->
      <div class="fb-customerchat"
        attribution="setup_tool"
        page_id=""
  theme_color="#007195">
      </div>

This option was not available for me in your setup process. But can confirm that it is working now. Cheers
