title: Facebook messenger plugin would not close
body: <p>I added the messenger plugin script and DIV right above the HEAD section on my HTML. </p>
  
  <p>The plugin does not work as described in <a href="https://developers.facebook.com/docs/messenger-platform/discovery/customer-chat-plugin#steps" rel="nofollow noreferrer">https://developers.facebook.com/docs/messenger-platform/discovery/customer-chat-plugin#steps</a></p>
  
  <p>Cannot close the text bubble. 
  Plugin do not default on hidden for mobile. 
  The attributes do not seem to work either. 
  Any thoughts?</p>
