hey I create a offline notifer as event

const { Events, EmbedBuilder} = require('discord.js');

module.exports = {

name: Events.PresenceUpdate,

async execute (oldStatus, newStatus, client) {

if (newStatus.user.id !== "xxx") return;

var bot = await client.users.fetch("xxx");

async function sendMessage (message) {

const embed = new EmbedBuilder()


.setColor("Blurple")

.setDescription(message);

var channel = await client.channels.fetch("xxx");

var member = await client.users.fetch("xxx");

await channel.send({ embeds: [embed] }).catch(err => {});

await member.send({ embeds: [embed] }).catch(err => {});

}

var timestamp = `<t:$(Math.floor(Date.now()/1000)):R>`;

if (!oldStatus && newStatus.status !== "offline") {

await sendMessage(`:warning: **Looks like ${bot.username} is offline!**\n${bot.username} (${bot.id}) became offline ${timestamp}, you might need to turn it back on to resolve this issue.`);
} else if (oldStatus.status !== "offline" && newStatus.status == "offline"){

     await sendMessage(`:information_source: **${bot.username} is back online!**\n${bot.username} (${bot.id}) was recently offline and as of now (${timestamp}) is back online!`);
}
  }
}

const { Events, EmbedBuilder} = require('discord.js');
