Embedding Google Drive PDF without "Click to Enable"

#1

I am trying to embed into a Coda document a PDF file hosted on my Google Drive.

I have followed Google’s instructions to obtain Embed code for an iframe. Then I put that HTML code on my web host and embedded the page into Coda. It works - except for the “Click to Enable” button on Coda.

For my own personal use it is not a big deal, but if I want to use this to present a portfolio of PDF documents to a client or to the public, it would be way nicer to have the PDF documents simply appear without having to “Enable” each one.

Is there any workaround?
