embed src html disappears

Hi,

I’m trying to embed a PDF document, so that it’s viewable in the page. I’ve gathered from a previous WP Support Post how to do this, but it is not working for me.

Below is the code I’ve tried. Also, I uploaded the PDF Document to my WP Site Media Library before. After clicking Update in the HTML Editor, the code disappears completely. I have tried this several different ways with no luck.

Thanks for your help.
