title: (discord.js) add role to author
body: <p>I am looking for help, my code handles a "message" event, and I am trying to make it add a role to the author of the comment</p>
  
  <p>My current attempt is</p>
  
  <p><code>client.on('message', msg =&gt; {msg.member.addRole("[role id]").catch(function(){});})</code></p>
  
  <p>however, it does not seem to be working for the various attempts I have made. Any help on this?</p>
  
  <p>Thank you!</p>
