title: Facebook error “App not setup:still in development mode”
body: <p>I am trying to create a facebook login and i tried to implement the same steps as specified in the Firebase web site. when the facebook login button is clicked an error saying.
  " App not setup: This app is still in development mode, and you dont have access to it.Switch to registered test user or ask an app admin for permissions"</p>
  
  <p>I know many people asked this. and the answer for resolving this error is to set the app as public in developers account. but my issue is where to set it. all the answers are outdated as the facebook developers account page have been changed and there is lot of changes and i could not locate it or fix it.
   thanks in advance.</p>
