There are some PowerUps like Resource Library and Cohort that give some options to display content outside of the course player. For example:
- Connecting a resource card in Resource Library to a PDF so that the PDF is downloaded for them 
- Same thing for Cohort, maybe you want a Cohort event to be "fill in the worksheet" 
For this it may be a better experience to access the PDF right then and there.
Getting the url of the download:
- Upload your files to a download lesson type inside of a course 
- Preview the course as a student and navigate to the download lesson 
- Right click on the download and copy the link to the clipboard 
- Paste it where you want to use it. If you are using Site Builder then you will need to select Custom Page first 
π Just so you know... the course does not need to be published to access this link. The link will be publicly available to anyone who contains the link
