Send Notification using Telegram when new IAP is purchased

index.js

const functions = require('firebase-functions');
const TelegramBot = require('node-telegram-bot-api');

const token = "***"
const chatID = 1024 // your telegram id, you must first send a message to your bot 

exports.notifyIAP = functions.analytics.event('in_app_purchase').onLog((event) => {
  const purchaseValue = event.valueInUSD;
  if (purchaseValue > 0) {
    const bot = new TelegramBot(token, {polling: false});
    return bot.sendMessage(chatID, "苹果宝到账: $" + (purchaseValue * 0.7).toFixed(2))
  }
});

你好，如何才能得到 firebase events，一个event被出发，firebase console里面好像没有可以指定后续动作的地方，谢谢

这是云函数的代码，打开云函数就能看到了。
