How can I add Upload-Lift to a custom page on my website?

[starkandco]

Hello, We have the Cloudlift uploader widget on our product pages... However; I want to add a secondary option- When the customer purchases our item and doesn't have their image ready or available then, I want them to be able to come back and upload anytime they are ready...  So I made a uploader page and I need to add this code 

{% comment %}
Upload-Lift widget element container
{% endcomment %}

however; I can seem to find the page I created?  Where do I find pages?  I am using the Dawn theme.

Here is my path...

When I search for it in the edit code.. Nothing comes up..
