Hi.
I want to call easyScroll, whe youser scroll up, because at the top of the page i have an iframe, and inside i have a scroll too.

    window.onscroll = function (e) {
        const scrollUp = this.oldScroll > this.scrollY;
        if (scrollUp && window.pageYOffset < 800) {
            easyScroll({
                'scrollableDomEle': window,
                'direction': 'top',
                'duration': 400,
                'easingPreset': 'linear',
                'onAnimationCompleteCallback': function () {
                    console.log('completed')
                }
            });
        }
        this.oldScroll = this.scrollY;
    }

Bui i got "completed" 95 times.
