我想讓機器人檢測用戶何時說話。在不和諧的文檔中我看到我需要使用該事件guildMemberSpeaking。這是代碼：const Discord = require('discord.js');const client = new Discord.Client();client.once('ready', () => {    console.log('Talkover is online!');})// Joins the voice channel with every tekstclient.on('message', async message => {    // Join the same voice channel of the author of the message    if (message.member.voice.channel) {        const connection = await message.member.voice.channel.join();    }});client.on('guildMemberSpeaking', (member, speaking) => {    if (speaking) {        console.log('speaking');    } else {        console.log('notspeaking');    }});由于某種原因，消息有效，但公會成員無法說話。我不知道我做錯了什么。
