如何在机器人中为人设置特殊权限？Discord.js

const Discord = require('discord.js');
const client = new Discord.Client();

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

client.on('message', (message) => {
  if (message.content.startsWith('!setPermission')) {
    // 获取要设置权限的用户
    const user = message.mentions.users.first();
    if (!user) {
      message.reply('请提及要设置权限的用户！');
      return;
    }

    // 获取要设置的权限
    const permission = message.content.split(' ')[2];
    if (!permission) {
      message.reply('请提供要设置的权限！');
      return;
    }

    // 获取要设置权限的角色
    const role = message.guild.roles.cache.find((r) => r.name === permission);
    if (!role) {
      message.reply('找不到该角色！');
      return;
    }

    // 将用户添加到角色中
    const member = message.guild.members.cache.get(user.id);
    member.roles.add(role)
      .then(() => {
        message.reply(`已为用户 ${user.tag} 设置权限 ${permission}！`);
      })
      .catch((error) => {
        console.error(error);
        message.reply('设置权限失败！');
      });
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
