Using xelatex, I got only the text, no pushbutton. Using pdflatex, I got a pushbutton, but it was not a hyperlink, just an image. What engine do you use to get this to work?

I ran pdflatex from a 2017 TeX Live install under Ubuntu, and viewed in Acrobat Reader.

Ahh, I think it is a viewer problem. Sadly, most viewers can not handle PDF attachments properly or at all.
