Add PDF workspace documents as a related link to records

What is the challenge?

Cannot find PDF workspace documents in the documents list when I try to link a PDF document I have added to Knowledge > Documents, when I add a related link to a record

What is the impact?

Have to manually link from the PDF document instead of the record itself
