client.on.ready = function() {
console.log("Client online!");
};

client.on.message_create = function(message) {
const guild = client.info.guilds.filter((guild) => guild.id == message.guild_id)[0];
const channel = guild.channels.filter((channel) => channel.id == message.channel_id)[0];

if(channel.id=="673488504524898304"){
console.log(message);
client.send(
