Hi Good question!

Usually this plug-in reads .pdf files, not example a .ppt file.

My experience with the plug-in that I either Search for (material) in my data base, while using slug name to locate the data field, and then file type of data should be there, a pdf.

In some cases I use direct (s3) link of the pdf, which you can find by going to the data field where is the pdf file, opening the field, and opening the .pdf by pressing the “See” button just next the folder, then you copy URL and paste the URL in the HMTL of the plug-in.

Btw. now I have again looked at your photo, no1, try to have something like this.
