I actually solved it a different way; by calling

document.getElementById('playpause').click()

Thanks anyway for the quick replies :)

Did this:

windyInit (options, windyAPI => {	
        const {store,map,overlays} = windyAPI;
	var overlay = store.get('overlay');
	var windMetric = overlays.wind.metric;
	store.set('overlay',this.config.showLayer);
	store.set('animation',true);
	overlays.wind.setMetric(this.config.windyMetric);
	map.setZoom(this.config.zoomLevel);
});

I tried, but got:
