How to implement iframe embed instead div embed

Forums: 

Hi! i'm trying to implement iframe embed instead div approach to avoid CSS conflict with the CSS of my site. Even following the steps described at https://h5p.org/creating-your-own-h5p-plugin The iframe is not populated with the H5P content event those sytles and scripts are not injected (inspected via network tab)

Can someone point me to right path to implement this?
