Fullpage.js and no-scroll in conflict


I have implemented fullpage.js on this project, but also Finsweet’s no-scroll class adder. The two seems two conflict, since scrollbar: true (fullpage) is somehow overriding the no-scroll (finsweet) on the body class. Is there some way I can keep both? Link below…

	//fullpage.js initialization
  new fullpage('#fullpage', {   
   //get it from https://alvarotrigo.com/fullPage/pricing/
    licenseKey: 'xxxx', 
    scrollingSpeed: 800,
    verticalCentered: false,
    scrollBar: true,



document.addEventListener('DOMContentLoaded', () => {
 document.querySelectorAll('.overlay-trigger').forEach(trigger => {
  trigger.addEventListener('click', function(){ 
    this.x = ((this.x || 0) + 1)%2; 
      document.querySelectorAll('.body').forEach(target => target.classList.add('no-scroll'));
      document.querySelectorAll('.body').forEach(target => target.classList.remove('no-scroll'));


@Alvaro_Trigo, any chance you can help me out?
Thanks a lot!

@Finsweet, any experience with this override?
