如何从服务器中随机选择成员id？Discord.js

const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS] });

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

client.on('messageCreate', async (message) => {
  if (message.content === '!randomMemberId') {
    const guild = message.guild;
    const memberIds = guild.members.cache.map((member) => member.id);

    const randomIndex = Math.floor(Math.random() * memberIds.length);
    const randomMemberId = memberIds[randomIndex];

    message.reply(`Random member id: ${randomMemberId}`);
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
