title: Python discord webhook doesn't really mention role
body: <p>I have a problem with mentioning role with discord webhook. I'm using discord_webhook library.
  When I try to mention a role webhook tags it and it looks fine but it didn't really ping users from that group. The message isn't also highlighted for them. That's not how the group mention should work</p>
  <p>In code my mention looks like this:</p>
  <pre><code>&lt;@&amp;823xxxxxxxxxxx01&gt;
  </code></pre>
  <p>But in real webhook:
  <a href="https://i.stack.imgur.com/JR2P7.png" rel="nofollow noreferrer">webhook</a></p>
  <p>Do you know how to make the webhook with notification highlithed for specific group? Of course my ping doesn't make classic discord ping sound (or notification)</p>
