如何获取messageReaction集合discord.js中的count字段

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('messageReactionAdd', (messageReaction, user) => {
  // 在这里处理messageReaction集合
});

client.on('messageReactionAdd', (messageReaction, user) => {
  const count = messageReaction.count;
  console.log(`反应数量: ${count}`);
});

client.on('messageReactionAdd', (messageReaction, user) => {
  const count = messageReaction.count;
  messageReaction.message.channel.send(`当前反应数量: ${count}`);
});
