title: Unable to Logout of Identity Provider Auth0 Office Addin
body: <p>I am developing a Microsoft Office Add-in that is using Auth0 to manage user logins. I am using Google SSO (identity provider) in Auth0.</p>
  <p>I was able to add the login capability to my  app by following this example on github: <a href="https://github.com/OfficeDev/Office-Add-in-Auth0" rel="nofollow noreferrer">https://github.com/OfficeDev/Office-Add-in-Auth0</a></p>
  <p>However I am now trying to add functionality to log the user out. I am calling the logout endpoint through a cors proxy (i host my own proxy that i use) as so:</p>
  <pre><code>https://cors-anywhere.herokuapp.com/https://{MY_AUTH0_DOMAIN}.auth0.com/v2/logout?
          federated&amp;
          client_id={MY_CLIENT_ID}&amp;
          returnTo={MY_RETURN_TO_URL}
  </code></pre>
  <p>The call will return a 200, but when I go to the login screen and sign in with google I am not presented with the screen to select my gmail. I am just logged into the app with the gmail i used the first time.</p>
  <p>The only thing that logs the user out of their gmail (identify provider) is by manually &quot;clearing the web cache&quot; in the add-in.</p>
  <p>I have tried following these instructions: <a href="https://auth0.com/docs/logout/log-users-out-of-idps" rel="nofollow noreferrer">https://auth0.com/docs/logout/log-users-out-of-idps</a>
  I setup the proper clientId for google, so that i am no longer using the dev keys.</p>
  <p>Has anyone successfully added logout functionality for an identify provider with auth0 in an office add-in?</p>
