如何在Discord.js嵌入中添加额外的字段？

const Discord = require('discord.js');

const client = new Discord.Client();

client.on('message', message => {
  if (message.content === '!embed') {
    const embed = new Discord.MessageEmbed()
      .setColor('#0099ff')
      .setTitle('Embed Title')
      .setURL('https://example.com')
      .setDescription('Embed Description')
      .addField('Field Title', 'Field Value', true) // 添加一个字段，并指定是否为行内显示
      .addField('Inline Field Title', 'Inline Field Value', true) // 添加一个行内字段
      .setTimestamp()
      .setFooter('Footer Text', 'https://example.com/icon.png');

    message.channel.send(embed);
  }
});

client.login('your-token');

const embed = new Discord.MessageEmbed()
  .setColor('#0099ff')
  .setTitle('Embed Title')
  .setURL('https://example.com')
  .setDescription('Embed Description')
  .addFields(
    { name: 'Field 1', value: 'Value 1', inline: true },
    { name: 'Field 2', value: 'Value 2', inline: true },
    { name: 'Field 3', value: 'Value 3', inline: false }
  )
  .setTimestamp()
  .setFooter('Footer Text', 'https://example.com/icon.png');
