Animation triggered by scrolling

Hello everyone, I’m trying to create an animated graphic novel on an interactive website, as a thesis project in a university of graphics and illustration.
In Adobe Muse, you can insert an animation in .oam format and decide to advance N animation frames every N scrolling pixel while visiting the web page. At this link an example made by me for another project, using Adobe Animate CC and Adobe Muse http://lanostraterrabeta.altervista.org/ (sorry for the wrong sizing of the animation in the desktop version).
As you can see, there is a difference to the triggered webflow interactions, as the animated elements belong to a video with frames, not to the interactions of individual elements.
With Webflow I tried to insert the same page that I linked before in a div using custom code, it seemed to work, but then some problems were created between the scroll of the original page and the scroll of the inserted page.
I did some research and I thought that a good solution could be to use After Effect to create animations, export a .js with Bodymovin, via javascript assign the management of timeline by scrolling the page … maybe the reasoning is right …or maybe not? In any case I do not know where to start to do this, my knowledge of coding have just started … if anyone has any solutions or ideas about it let me know! Thanks so much
