I know this question is very old and perhaps you already solved your issue, but for anyone on the internet who might be looking for an answer...
I have been looking for this recently, following a guide I found on GitHub Gist
https://gist.github.com/tzmartin/1cf85dc3d975f94cfddc04bc0dd399be
More specifically, the option to embed a certain page of pdf using
<iframe src="https://docs.google.com/viewer?srcid=[put your file id here]&pid=explorer&efh=false&a=v&chrome=false&embedded=true" width="580px" height="480px"></iframe>
The best I could fing was this article (I suppose from a long time now)
https://weekly-geekly.github.io/articles/111647/index.html
HOWEVER, I tried modifying the attributes and the result was simply a redirect to
https://drive.google.com/file/d/[ID]/edit
https://drive.google.com/file/d/[ID]/preview
or
https://drive.google.com/file/d/[ID]/view
AS OF MAY 2020, THIS SOLUTION PROBABLY DOESN'T WORK
