How to embed Pages ePub on Squarespace website?

Does anyone know how to generate code or otherwise to drop an ePub (or any other video-supporting file format from Pages) into a Squarespace website? While I know I can export Pages to PDF and upload PDF to Squarespace, that flattens the videos I've embedded into Pages. I've also tried a couple online converters (ePub to HTML) but frankly don't really know what to do with the multiple files produced. Any input most appreciated! Thank you.
