I cannot see my commands

const { Client, GatewayIntentBits, Collection } = require('discord.js');
const fs = require('fs');
const config = require('./config.json');

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
    GatewayIntentBits.MessageContent,
    GatewayIntentBits.GuildMembers
  ]
});

client.commands = new Collection();

// Load commands dynamically from the 'commands' folder
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
  const command = require(`./commands/${file}`);
  client.commands.set(command.data.name, command);
}

client.once('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('interactionCreate', async (interaction) => {
  if (!interaction.isCommand()) return;

  const command = client.commands.get(interaction.commandName);
  if (!command) return;

  try {
    await command.execute(interaction);
  } catch (error) {
    console.error(error);
    await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
  }
});

client.login(config.token);
