HarmonyOS 设置了锁屏通知，但是锁屏后没有显示通知栏

let notificationRequest: notificationManager.NotificationRequest = { 
  id: 1, 
  notificationSlotType: notificationManager.SlotType.SOCIAL_COMMUNICATION, 
  content: { 
    notificationContentType: notificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT, // 普通文本类型通知 
    normal: { 
      title: 'test_title', 
      text: 'test_text', 
      additionalText: 'test_additionalText', 
    } 
  } 
};
