HarmonyOS 鸿蒙Next getWantAgent的使用

@Entry @Component export struct AboutUs {

publishNotification() { // 通知发送 let wantAgentObj = null; // 用于保存创建成功的wantAgent对象，后续使用其完成触发的动作。

// 通过WantAgentInfo的operationType设置动作类型。
let wantAgentInfo = {
  wants: [
    {
      deviceId: '',
      bundleName: 'com.example.test',
      abilityName: 'com.example.test.MainAbility',
      action: '',
      entities: [],
      uri: '',
      parameters: {}
    }
  ],
  operationType: wantAgent.OperationType.START_ABILITY,
  requestCode: 0,
  wantAgentFlags:[wantAgent.WantAgentFlags.CONSTANT_FLAG]
}

// 创建WantAgent
wantAgent.getWantAgent(wantAgentInfo, (err, data) => {
  if (err) {
    console.error('[WantAgent]getWantAgent err=' + JSON.stringify(err));
  } else {
    console.info('[WantAgent]getWantAgent success');
    wantAgentObj = data;
  }
});

// 构造NotificationRequest对象
let notificationRequest = {
  content: {
    contentType: Notification.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT,
    normal: {
      title: 'Test_Title',
      text: 'Test_Text',
      additionalText: 'Test_AdditionalText',
    },
  },
  id: 1,
  label: 'TEST',
  wantAgent: wantAgentObj,
}

Notification.publish(notificationRequest, (err) => {
  if (err) {
    console.error(`[ANS] failed to publish, error[${err}]`);
    return;
  }
  console.info(`[ANS] publish success `);
});

}

build(){ Column(){ Text(“关于我们”)

    Button('发送通知')
      .width('50%')
      .margin({bottom:10})
      .onClick(() => {
        this.publishNotification()
      })
}

}

}

无效参数什么意思 安装官方文档咋不对呢 有没有大佬解释一下
