@LDykes5 What CMS do you use for your website?
As @Ben_M said, there’s no way to add a CTA to a file hosted by your HubSpot. The best thing to do would be to create a new page on your CMS and embed the PDF then add a HubSpot CTA popup to that page to gather demo requests.
Doing this would allow:
- HubSpot CTA Popup to work
- Create a dedicated and branded page URL to share
- Allow HubSpot to track web activity on the page
