How to get all Photoshop styles using photoshop scripting?

[qFamouse]

I want to randomly apply styles to my ArtLayers. To do this, I tested the applyStyle function.

It works!)

But to solve my task I need all styles. I can't find it in the documentation (photoshop-javascript-ref-2020).

Can you suggest something?

A track where you must know the path of your PS presets :

var stylesFound = false;
main();
if (!stylesFound) {
	alert("No styles found. You should verify the path to your Photoshop style presets.");
}
function main() {
	var styleFolder = Folder('/c/Program Files (x86)/Adobe/Adobe Photoshop CS5/Presets/Styles');
	// Set all style names in an array
	var styleList = styleFolder.getFiles(/\.(asl|)$/i);
	//styleList = styleFile.substring( 0, docRef.name.indexOf('.') );
	// STOP if not any ASL file found
	stylesFound = true;
	if (styleList.length==0) {
		stylesFound = false;
		return;
	}	
	// Random
	var rnd = Math.floor(Math.random() * styleList.length);
	var styleName = styleList[rnd].name;
	alert(styleName);
}

activeDocument.suspendHistory('Apply random style', 'main()');

    activeDocument.artLayers.add();
    var stylesIndexes = applyStyles();
    activeDocument.activeLayer.remove();
    applyStyles(stylesIndexes[Math.floor(Math.random() * stylesIndexes.length)])
}

function applyStyles(idx) {
