In addition to @Looky's suggestion, SVGator has now added a Javascript API. You need to export from SVG/Javascript setting the trigger as "Programmatic", then you can initialize your player like this...

const element = document.getElementById('eDuWOrNCbmP1');
var player = element ? element.svgatorPlayer : {};

if (player.play) {
    player.play();
}

Then, in your onClick event, you can simply call...

player.stop();
