I didn't had an error but looking for a direction, should I use a plugin ? Which one? Other ideas...
From what I found, there is basically 2 options to create animated presentation in MDX documents; use an app that creates html5 containers (Google Web designer, Tumult Hype...) and find a way to present them into an MDX document or, to use third party apps were you only have to put an iframe in the page.
After trying many options, I reverted to use iframes for the simplicity. Tried many apps like Visme, Greensock and others, to finally go with Reveal.js-Slides.com.
First post here, got a "-1" and answered my own question... Hum.
Thanks.
