title: code-push: How to find deployment keys for the app added from appcenter website ( add new app option )
body: <p>I added a react-native android app using the <strong>Add new app</strong> option on appcenter website.
  Now i need to find the deployment keys for the same.
  I tried<br>
   <strong><em>code-push deployment list  YourAppName --displayKeys</em></strong><br>
  but it didnt return keys.</p>
  
  <p>Although when I add the app using CLI
       <strong><em>code-push app add YourAppName  android react-native</em></strong><br>
  and then retrieve the keys using earlier command it works fine and gives both staging and pro keys.</p>
  
  <p>Please somebody explain this.</p>
  
  <p>Thanks.</p>
