Link widget to download Primary Content (Attached file) of a wtDocument

Hi all,

I'm working on a POC where I'm using PTC Navigate(1.5.1). Similar to 'View Document' ootb app in the Landing Page, I'm developing an app 'View Issue Document' app where the user can see only the Issue Documents(a sub-type of wtDocument). I am able to get only the Issue docs to be displayed  but I can't download its primary content.

• Can the ootb app (View Document) configured to see only the subtype of wtDocument?
• If not, then which services should I use in my custom app to achieve the download functionality?

Thanks in Advance.

Regards,
