title: Can I put an app to TestFlight with only appStoreConnect Account
body: <p>I need to upload a build of my app to test flight, Now my client has given me an admin role in app store connect only and didn't add my apple id in developer.apple.com.</p>
  
  <p>Can I upload the app to test flight?</p>
  
  <p>If yes, How can I do that?
  If no, what is the next procedure I should follow?</p>
  
  <p>I am confused as in why the developer portal and app store connect have been separated and need to know about it too.</p>
  
  <p>P.S: This is the first time I am uploading app, so bear with me.</p>
