How do I make subcommands?

const { SlashCommandBuilder } = require("discord.js");

module.exports = {
  cooldown: 5,
  data: new SlashCommandBuilder()
    .setName("info")
    .setDescription("Get info about a user or a server!")
    .addSubcommand((subcommand) =>
      subcommand
        .setName("user")
        .setDescription("Info about a user")
        .addUserOption((option) =>
          option.setName("target").setDescription("The user")
        )
    )
    .addSubcommand((subcommand) =>
      subcommand.setName("server").setDescription("Info about the server")
    ),
    async execute(interaction) {
        
      },
};
