删除邮件Bot Discord

Question

const Discord = require("discord.js");
const client = new Discord.Client();
const prefix = "!";

client.on("ready", () => {
    console.log("I am ready!");
    client.user.setPresence( {
        status: "online",
        game: {
            name: "MyBOT",
            type: "PLAYING"
        }
     });
 });

 const fetchedMessages = await msg.channel.fetchMessages();
 const amount = 50

client.on("message", msg => {
    if (message.content.toLowerCase().startsWith(prefix + "clearchat")) {
        client.on('message', message => {
           if (message.reply('!say')) {
               for (let i = 0; i < amount; i++) {
               await fetchedMessages[i].delete()
               await msg.channel.bulkDelete(AMOUNT)
    }};
});

const token = ("my token");
client.login(token);

您能告诉我如何实现吗？是用于删除消息的自定义漫游器

而且先声不起作用，我不知道他们为什么可以在这两件事上帮助我？我是初学者
