If you would like to add your own checkout link instead of using the automatic one, you can do this by following the instructions below.
Scroll down to the Order status page section
Paste the following code into the field titled Additional scripts
<div id='downloads' class='content-box' style="margin-top: 25px;">
<div class='content-box__row'>
<a href='http://{{shop.domain}}/apps/downloads/orders/view/{{order.email}}/{{order.id}}' class='btn'>
Download My Purchases
</a>
</div>
</div>
<script type='text/javascript'>
document.addEventListener('sky-pilot-ready', function(){
SkyPilot.target = '#downloads';
SkyPilot.hide_unless_downloads('{{order.email}}', '{{order.id}}', '{{shop.permanent_domain}}');
});
</script>
Click the Save button
