title: Facebook API - How to add application to group in developer mode
body: <p>I have troubles with adding my application to group for any test user.
  I've created two test users and one of them has group and he is an admin there and I wrapped those users into test application. </p>
  
  <p>I've added two permissions for groups (groups_access_member_info, publish_to_groups). In user settings I see my application but in group settings I can't add my application.</p>
  
  <p>I need this because I would like to make request from facebook graph API.</p>
  
  <p>Regards</p>
