      // 1. Disconnect the client to clear local tokens.
      await client.disconnect();
      _isAuthenticated = false;
      // 2. Clear all WebView cookies to ensure a fresh login prompt on the next connect attempt.
      await cookieManager.deleteAllCookies();
      debugPrint("OneDrive logout successful and web cookies cleared.");
