Is there a way to add PDFs to a Hub site?
Yes. Assuming you have a local copy of the PDF, from your organization, just do an Add Item > From my computer.
Choose the PDF and upload it, fill out all your metadata.
Share it to the appropriate group and publicly (just like all your other datasets).
You'll then need to turn on the new Search API settings. This blog has more info: Enabling New Beta Search in ArcGIS Hub
