How to download Pdf files from HTML EXE?

Hi
How can I download Pdf files from HTML EXE? Please help!

From https://www.htmlexe.com/help/externallinks
<a target="_heopenit" href="mydocument.pdf">Open this PDF document</a>

@gdgsupport this is the screen shot. What should I do next? I want to download those left side Pdf files.

You would have to make a dedicated button in the toolbar. This button should call an HEScript script that opens the current PDF in an external viewer.
