title: Mention userid with discord bot
body: <pre><code>if message.content == '-CheckNico':
          await message.channel.send(Nico) 
  </code></pre>
  <p>I need to mention a user of discord  on (message content), for example, instead of <code>-CheckNico</code> as a command, I have to  mention the user id on my server.  example --&gt; - <code>@2647388376563834</code> (user id)</p>
  <p>I don't have any idea how to do this.</p>
