node.js-duscird.js获取相关用户的名称

我有一个命令，其中一个用户实际上亲吻了另一个用户

输出是一条消息@User1 kissed @User2

但是我想让用户只写名字，而不是标签，就像这样user1 kissed user2

理论上，一切都应该是这样

`**${message.author.username}** kissed **${userToKiss.username}**`

但是如果message.author定义了，那么就没有了userToKiss我最终得到了这个

user1 kissed undefined

如何获取第二个用户的名称？

const { Command } = require('discord.js-commando');
const Discord = require('discord.js');

module.exports = class KissCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'kiss',
      memberName: 'kiss',
      group: 'reywl',
      description: 'Kiss the mentioned user',
      guildOnly: true,
      args: [
        {
          key: 'userToKiss',
          prompt: 'Please select the member you want to kiss.',
          type: 'member',
          default: 'isempty',
          wait: 0.0001
        }
      ]
    });
  }
  
  run(message, { userToKiss }) {
    if (userToKiss == 'isempty') {
        return message.channel.send('Please select the member you want to kiss.')}
    if (userToKiss.id == message.author.id) {
      return message.channel.send('You cant kiss yourself!');
    }
    else {
        const embed = new Discord.MessageEmbed()
        .setDescription(`**${message.author}** kissed **${userToKiss}**`)

        message.channel.send(embed)
    }
    setTimeout(() => message.delete(), 1000)
}};
