How to create a channel and send a message to it when user logined to server?

Question

How add channel and send message to it by discord bot when user login? Message should include hyper link button.

const Discord = require("discord.js");
const config = require("./config.json");
const { MessageActionRow, MessageButton } = require("discord.js");
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });
const prefix = "!";
client.on("messageCreate", function (message) {
    let guild = message.guild;
    if (message.author.bot) return;
    if (!message.content.startsWith(prefix)) return;

    const commandBody = message.content.slice(prefix.length);
    const args = commandBody.split(" ");
    const command = args.shift().toLowerCase();

    if (command === "ping") {
        const timeTaken = Date.now() - message.createdTimestamp;
        message.reply(`Pong! This message had a latency of ${timeTaken}ms.`);
    } else if (command === "sum") {
        const numArgs = args.map((x) => parseFloat(x));
        const sum = numArgs.reduce((counter, x) => (counter += x));
        message.reply(`The sum of all the arguments you provided is ${sum}!`);
    } else if (command === "channel") {
        // Create a new text channel
        guild.channels
            .create("nft-checking", { reason: "Needed a cool new channel" })
            .then(console.log)
            .catch(console.error);
    }
});

// client.on("ready", (client) => {
//     client.channels.get("938800178314485823").send("Hello here!");
// });
client.login(config.BOT_TOKEN);
console.log("Discord server is running.");
