title: How can I execute certain part of code from a reaction on a private message (not a channel message) with Discord.JS?
body: <p>I am creating a Discord bot that sends private welcome messages to users that enter my server.</p>
  <p><img src="https://i.stack.imgur.com/ZKAdK.png" alt="My Discord bot private message screen" /></p>
  <p>I want to execute some lines of code (I want to add different roles to the users) which differ if the user reacts with those three emojis.<br />
  Online I found guides that refer to channel messages only and I don't understand which approach to use with private messages.<br />
  Thank you!</p>
