title: How do you get a linked message in discord.js?
body: <p>I want to add a mod command to my discord.js bot that adds a message to the starboard. The way I want it to work is if someone types in !mod starboard _____ (message link) the linked message will be added to the starboard. I know how to add that message to the starboard once I have it but I don't know how to get the message. The code below is what I have so far, but it says it can't read &quot;first&quot; of &quot;undefined.&quot; What is the proper syntax?</p>
  <p><code>const targetmessage = message.mentions.message.first();</code></p>
