如何从hubot向rocketchat发送格式化消息？

// 引入rocketchat的API库
const RocketChatAPI = require('rocketchat-api');

module.exports = (robot) => {
  // 配置rocketchat的API连接
  const api = new RocketChatAPI({
    host: 'your-rocketchat-host',
    username: 'your-username',
    password: 'your-password',
  });

  // 监听hubot的消息事件
  robot.hear(/send formatted message/i, (res) => {
    // 构建格式化消息的内容
    const formattedMessage = `
      *Hello, this is a formatted message!*
      [Link](https://example.com)
      ![Image](https://example.com/image.jpg)
    `;

    // 使用rocketchat的API发送消息
    api.sendMessage({
      roomId: 'your-room-id',
      text: formattedMessage,
    }).then(() => {
      res.send('Formatted message sent successfully!');
    }).catch((error) => {
      res.send(`Failed to send formatted message: ${error}`);
    });
  });
};
