如何设置一个通知按钮

import { BusinessError } from '@kit.BasicServicesKit';
import { notificationManager } from '@kit.NotificationKit';
import { wantAgent , WantAgent } from '@kit.AbilityKit';

// publish回调
let publishCallback = (err: BusinessError): void => {
  if (err) {
    console.error(`publish failed, code is ${err.code}, message is ${err.message}`);
  } else {
    console.info("publish success");
  }
}
let wantAgentObj:WantAgent; // 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:wantAgent.WantAgentInfo = {
  wants: [
    {
设置事件名
      parameters: {},
    }
  ],
  operationType: wantAgent.OperationType.SEND_COMMON_EVENT,
  requestCode: 0,
  wantAgentFlags: [wantAgent.WantAgentFlags.CONSTANT_FLAG],
};
// 通知Request对象
let notificationRequest: notificationManager.NotificationRequest = {
  id: 1,
  content: {
    contentType: notificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT,
    normal: {
      title: "test_title",
      text: "test_text",
      additionalText: "test_additionalText"
    }
  },
  actionButtons: [
    {
回复',
      wantAgent: wantAgentObj
    }
  ]
};
notificationManager.publish(notificationRequest, publishCallback);
