Hi!
I'm able to preview an attached PDF @ service desk agent view (when working on a ticket).
Following screenshot displays a ticket with a PDF attached.

When I click on it a preview pops up.

Now if I view the customer request @ customer portal, I only get the option to download the file - no preview here.

Is it possible to configure a preview for PDFs as well @ customer portal?
It works for attached images both in the portal and in the project, by the way.
Thank you in advance!
Cheers,
Dominik
