| 9928 `google-signin-aware` is used to enable authentication in custom elements by |  | 
| 9929 interacting with a google-signin element that needs to be present somewhere |  | 
| 9930 on the page. |  | 
| 9931 |  | 
| 9932 The `scopes` attribute allows you to specify which scope permissions are require
       d |  | 
| 9933 (e.g do you want to allow interaction with the Google Drive API). |  | 
| 9934 |  | 
| 9935 The `google-signin-aware-success` event is triggered when a user successfully |  | 
| 9936 authenticates. If either `offline` or `offlineAlwaysPrompt` is set to true, succ
       essful |  | 
| 9937 authentication will also trigger the `google-signin-offline-success`event. |  | 
| 9938 The `google-signin-aware-signed-out` event is triggered when a user explicitly |  | 
| 9939 signs out via the google-signin element. |  | 
| 9940 |  | 
| 9941 You can bind to `isAuthorized` property to monitor authorization state. |  |
