  * Send toast notifications (brief auto-expiring OS window element) to your user.
  * Can also be used with the Notification Web API.
  *
- * This package is also accessible with `window.__TAURI__.notification` when [`build.withGlobalTauri`](https://tauri.app/v1/api/config/#buildconfig.withglobaltauri) in `tauri.conf.json` is set to `true`.
- *
- * The APIs must be added to [`tauri.allowlist.notification`](https://tauri.app/v1/api/config/#allowlistconfig.notification) in `tauri.conf.json`:
- * ```json
- * {
- *   "tauri": {
- *     "allowlist": {
- *       "notification": {
- *         "all": true // enable all notification APIs
- *       }
- *     }
- *   }
- * }
- * ```
- * It is recommended to allowlist only the APIs you use for optimal bundle size and security.
