How can I automatically grant access to a client for a user without prompting the user?

I’m using the angular sample to get started so I modified mine to be:

 // Initialization for the angular-auth0 library
    angularAuth0Provider.init({
      clientID: AUTH0_CLIENT_ID,
      domain: AUTH0_DOMAIN,
      responseType: 'token id_token',
      audience: AUTH0_AUDIENCE,
      redirectUri: AUTH0_CALLBACK_URL,
      scope: REQUESTED_SCOPES,
      leeway: 30,
      prompt: 'none'
    });

But it’s still prompting “My New App would like access to your mynewapp account”. Anything else I could be missing?
