Scroll Animation Help

Hello,
I want to rebuild this scroll animation.

https://amandamartocchio.com/

I know that I need either fullpage.js or scrollify for the scroll Snap. But I don’t know how to exclude the hero section from that effect. I have also no Idea how to realize the effect on the firts scroll.

It kinda worket for me but not really.
