PS script for toggling visibility of layers based on their names

I work with Photoshop for a team that creates animated desktop pets. In a summary, when we work with asymmetrical characters, there are a lot of layers and groups that need to be turned on or off when we need to export the frames of the character looking to the other side. So there are layers that are called "Eye Asym", "Left Arm Asym", "Right Ear Asym", etc., and those can be inside of multiple groups that are inside of other groups.

I'm trying to set a script that can toggle on/off all groups or layers that contain " Asym" on the name, all at once.

After a lot of research, and multiple failed attempts, the only one I have found that is close to work is this one: https://community.adobe.com/t5/photoshop-ecosystem-discussions/script-request-for-toggling-visibilit... (General expression changed for my case)

#target photoshop

var re = /.* Asym/; // a reg exp

var matches = collectNamesAM(re); // get array of matching layer indexes

for( var l = 0; l < matches.length; l++ ){

  makeActiveByIndex( matches, false );

  // do something with layer

  var docLayer = app.activeDocument.activeLayer;

  docLayer.visible=docLayer.visible==false;

  // test matches with alert

  //alert(app.activeDocument.activeLayer.name);

} // next match if any

function collectNamesAM(re){

  var allLayers = new Array();

  var startLoop = Number( !hasBackground() );

  var endLoop = getNumberOfLayer();

  for( var l = startLoop;l < endLoop; l++){

  while( !isValidActiveLayer( l ) ) {

  l++;

  }

  if( getLayerNameByIndex( l ).match(re) != null){

  allLayers.push( l );

  }

  }

  return allLayers;

};

function getActiveLayerIndex() {

  var ref = new ActionReference();

  var res = executeActionGet(ref).getInteger( 1232366921 )

  - Number( hasBackground() );

  res == 4 ? res++:res // why the skip in this doc?

  return res;

  ref.putProperty( 1349677170 , propName); // TypeID for "Prpr"

  // 'Lyr ", idx

  ref.putIndex( 1283027488, idx );

  var desc =  executeActionGet( ref );

  var type = desc.getEnumerationValue( propName );

  var res = typeIDToStringID( type );

  return res == 'layerSectionEnd' ? false:true;

};

//////////////////////////////////////////////////////////////////////////////*/

function hasBackground(){

  var res = undefined;

  try{

  var ref = new ActionReference();

  ref.putProperty( 1349677170 , 1315774496);

  ref.putIndex( 1283027488, 0 );

  executeActionGet(ref).getString(1315774496 );;

  res = true;

  }catch(e){ res = false}

  return res;

};

function makeActiveByIndex( idx, forceVisible ){

  try{

  var desc = new ActionDescriptor();

  var ref = new ActionReference();

  ref.putIndex(charIDToTypeID( "Lyr " ), idx)

  desc.putReference( charIDToTypeID( "null" ), ref );

  desc.putBoolean( charIDToTypeID( "MkVs" ), forceVisible );

  executeAction( charIDToTypeID( "slct" ), desc, DialogModes.NO );

  }catch(e){ return -1;}

};

function getNumberOfLayer(){

  var ref = new ActionReference();

  ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );

  var desc = executeActionGet(ref);

  var numberOfLayer = desc.getInteger(charIDToTypeID("NmbL"));

  return numberOfLayer;

};

function getLayerNameByIndex( idx ) {

  var ref = new ActionReference();

  ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID( "Nm  " ));

  ref.putIndex( charIDToTypeID( "Lyr " ), idx );

  return executeActionGet(ref).getString(charIDToTypeID( "Nm  " ));;

};

But it doesn't work properly, because it toggles multiple times in a row the top group of layers that contains a layer with the word " Asym" inside, instead of toggling those layers once.

I appreciate any help you can provide.

That Script referred to a specific name, so here is one with a few changes: 

// hide or show layers with a certain name-part;
// 2022, use it at your own risk;
if (app.documents.length > 0) {
    var thisName = "Asym";
    var theLayers = collectLayersByName(thisName);
    for (var x = 0; x < theLayers.length; x++) {
        if (theLayers[x][3] == true) {var idhide = stringIDToTypeID( "hide" )}
        else {var idhide = stringIDToTypeID( "show" )};
        var desc22 = new ActionDescriptor();

OMG yes! why didn't I find this one during all the research I made!?

It works with predefined names. Is there a way to make it works with Reg Ex? or at least to work with names that contain a specific word within?

Because all the names of the layers I need to toggle are different, but they all share the same word "Asym"

Ie. "Left Ear Asym", "Right Arm Asym", "Left Eye Asym", etc.
