On scroll event - go to anchor on scroll down / up

Design help Custom code
1

Iv been struggling im guessing like many others with the Fullpage.js plugin.
The plugin clashes with Webflow interactions and wont link or react to anchors at all.

I was hoping there might be a work around it using on scroll events that would go to a specific anchor with something similar to this?

window.onscroll = function() {myFunction()}; function myFunction() {
if (document.body.scrollTop > 350 || document.documentElement.scrollTop > 350) {
    document.getElementById("myImg").className = "slideUp"; }

Any help would be appreciated.
