我试图为我的机器人发出 ping 命令，这是我的代码

client.on('message', message => {
  if (message.content === '+ping') {  
    message.channel.send(`Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  }
});

但是我最终收到以下错误

C:\Users\ujjwa\Desktop\All Disc\Test all\index.js:236
    message.channel.send(`Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
                                     ^

ReferenceError: m is not defined

我试图让我的 discord.js bot 在 ping 时发送一条消息。我不确定如何执行此操作，因此我参考了此代码：

client.on('message', message => {
    if (message.content === '<@745648345216712825>') {
        message.channel.send('Message Here');
    }
});

但是，这不起作用。

此外，当一个人提到特定用户时，我的机器人是否有可能做出响应，例如，如果用户在机器人响应的消息中的任何地方提到了我？如果是的话，你能告诉我怎么做吗？
