How do I show file uploads in my Zoho Creator approval workflow?

As far as I can tell I'm not able to add the file upload field to the approval workflow show fields list.

As a work around I'm making a plain text field that links to the files URL. But I'm not sure how to get a link to that url that will me to preview the attatchment or even download it.

Any help would be appreciated.
