Google packaged app - identity API - removeCachedAuthToken

Question

[google chrome 28] I am using chrome.experimental.identity API in a packaged app and getAuthToken works fine - get's token with which I can get user info, etc. I understand that the identity API is moving out from being experimental to the trunk so as from chrome 29 I will be able to use chrome.identity and remove "experimental" permission from my manifest.

Q: If I want to make a logout button is removeCachedAuthToken the way to go about it? I tried to use it in the experimental.identity but it does nothing.

To revoke token use this function from google sample app.

function revokeToken() {
    user_info_div.innerHTML = "";
    chrome.identity.getAuthToken({ interactive: false }, 
      function (current_token) {
        if (!chrome.runtime.lastError) {
          // @corecode_begin removeAndRevokeAuthToken
          // @corecode_begin removeCachedAuthToken
          // Remove the local cached token
          chrome.identity.removeCachedAuthToken({token: current_token}, function(){});
          // @corecode_end removeCachedAuthToken

          // Make a request to revoke token in the server
          var xhr = new XMLHttpRequest();
          xhr.open(
          "GET", 
          "https://accounts.google.com/o/oauth2/revoke?token=" + current_token);
            
          xhr.send();
          // @corecode_end removeAndRevokeAuthToken

          // Update the user interface accordingly
          changeState(STATE_START);
          sampleSupport.log("Token revoked and removed from cache. " + 
            "Check chrome://identity-internals to confirm.");
        }
    });
}
