Implementation

@override
Future<Map<String, dynamic>> startMultiSessionUssd(
  String ussdCode, {
  int? subscriptionId,
}) async {
  try {
    final Map<String, dynamic> arguments = {'ussdCode': ussdCode};
    if (subscriptionId != null) {
      arguments['subscriptionId'] = subscriptionId;
    }

    final result = await methodChannel.invokeMethod<Map<Object?, Object?>>(
      'startMultiSessionUssd',
      arguments,
    );
    return Map<String, dynamic>.from(result ?? {});
  } on PlatformException catch (e) {
    debugPrint('Error starting multi-session: ${e.message}');
