Çözüldü Botun Girdiği Sunucuya Nasıl Oto Mesaj Attırırım?

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

client.on("guildCreate", guild => {
    let channelID;
    let channels = guild.channels.cache;

    channelLoop:
    for (let key in channels) {
        let c = channels[key];
        if (c[1].type === "text") {
            channelID = c[0];
            break channelLoop;
        }
    }

    let channel = guild.channels.cache.get(guild.systemChannelID || channelID);
    channel.send(`Mesaj buraya!`);
});
