如何让 Discord.js 当我们提到（@）机器人时，机器人以本地图片响应？

Question

I am a newbie to JavaScript. I want to make my discord server's bot responding with local picture on my computer while anybody mentions(@) it. I have tried multiple methods,
this is the one I follow the documentation:

client.on('message', (message) => {
 if (message.mentions.has("My Bot's ID")) {
  const attachment = new MessageAttachment('./images/image1.png');
  return message.channel.send(`Hi ${message.author},`, attachment);
 }
});

This one failed, as well as a few older version methods I tried. Some of them not even operate, so I deleted them.

Also, I can't find any other materials besides the documentation for the version(12.3.1).

MessageMentions is an object. You are looking for the MessageMentions.users Collection.

client.on('message', (message) => {
 if (message.mentions.users.has("My Bot's ID")) {
  // message.mentions.users
  const attachment = new MessageAttachment('./images/image1.png');
  return message.channel.send(`Hi ${message.author},`, attachment);
 }
});
