title: How to DM user using discord.js
body: <p>I'm making a bot on Discord.js. The bot will give a role to every user. The problem is I want the bot DM the role to each user. The code was just not working for me.</p>
  
  <p>What I've tried:</p>
  
  <p><code>client.users.get('id').send('Blabla')</code>, but it didn't work.</p>
  
  <p><code>message.author.send("Blabla.")</code> would only send the message to the author.</p>
  
  <p><code>message.channel.send("Blabla")</code> would only send the message to a channel.</p>
