How to output File Upload Media Url into email action message

Just using the cs form with the file upload save url in field. And was hoping instead of attaching the file to the email I could print the url just like how it auto saves it into the field. I tried these different fields on email action and all seem to output nothing.

{{dc:file:upload name=“file_upload”}}
{{dc:form:data key=“file_upload”}}
{{dc:file:all}}

Sidenote other aspects of the form are working great only just started the past week trying it out e.g. I am using it with way for internal contact for for staff with option to email users and this with combination of loop providers and filtering is working great for internal small dashboard reporting side and not having to require any other plugins.
