如何允许用户@进行其他嵌入？ Discord Bot JS

Question

案例“嵌入”：

    ``` const embed = new Discord.MessageEmbed()
     .setTitle ('User Information')
     .addField('User', message.author.username)
     .addField('Version', version)
     .addField('Current Server', message.guild.name)
     .setThumbnail(message.author.displayAvatarURL())
     .setColor(0xffcc5f)
     .setFooter('Stay Hydrated!')
     message.channel.send(embed);
     message.channel.mentions.username.first(embed);
    break;```

这是原始代码，我想知道如何让用户这样做！嵌入@person，它将显示有人嵌入。
