How to reverse stroke?

Question

JavaScript

Good day)
I'm using the anime.js library to animate the rendering of the svg stroke, everything works as it should, except for one thing, I can't render the svg stroke back on a certain event. Here is the code:

function makeStroke(){
var drawer = anime({
        targets: '.header-img path',
        strokeDashoffset: [anime.setDashoffset, 0],
        easing: 'easeInOutSine',
        duration: 2000,
        delay:0,
        direction: 'alternate',
        loop: false,
        });
        var filler = anime({
        targets: '.header-img path',
        easing: 'easeInOutSine',
        duration: 1000,
        fill:'#000',
        delay:2000,
        direction: 'alternate',
        loop: false,
        });
}

function removeStroke(){
// Не знаю как сделать
}

Thanks in advance)
