Add a Reddit share button

I really like this lightweight plugin and all the documentation for additional features is awesome.

I just noticed a tiny mistake on this document
https://sharedcountsplugin.com/2019/03/27/add-a-reddit-share-button/

The line
$link['link'] = 'https//www.reddit.com/submit?url=' . $link['url'];
is missing the colon in https://

It might also be useful to put the colour css in the doc

add_action( 'wp_head', function () { ?>
  <style>
    .shared-counts-button.reddit {
      background-color: #ff4401;
    }
    .shared-counts-button.reddit:hover {
      background-color: #cd3600;
    }
  </style>
<?php } );
