Indesign scripting - apply PDF Tags to styles

Hello Team,
Im writing a script where, for an active indesign document, for each paragraph styles we need to add PDF - tags.
Data for parastyles to pdf tags will be supplied from csv file, dynamically.
For example, para style "1hd" will be added as "H1" - PDF tag.
Below is the code, I have tried.

// Define the CSV file path
var csvFilePath =
  "\path\csvFileName.csv";
// Initialize an array to store matching style names
var doc = app.activeDocument;
var matchingStyles = [];
var mappingMessages = [];
var message = "";
var csvRow = "";
var indesignStyle = "";
var pdfTag = "";
var csvRows = "";
var paraStyles = [];
var rowCount = "";
var style;

// Create UI with button to map styles
app.scriptPreferences.userInteractionLevel =
  UserInteractionLevels.interactWithAll;

var dialog = new Window("dialog", "PDF Tag testing");

var mapStylesButton = dialog.add("button", undefined, "Map styles");
mapStylesButton.onClick = function () {
  csvFile = File(csvFilePath);
  if (!csvFile.exists) {
    alert("CSV file not found!");
    return;
  }
  // Read CSV content
  csvFile.open("r");
  csvContent = csvFile.read();
  csvFile.close();
  //  alert("CSV Content "+csvContent);

  csvRows = csvContent.split("\n");
  rowCount = csvRows.length;
  //alert("Number of rows: " + rowCount);

  // Fetch paragraph styles in the active document
  paraStyles = doc.paragraphStyles.everyItem().getElements();
//   alert(
//     "Fetched " + paraStyles.length + " paragraph styles from the document."
//   );

  // Iterate through CSV rows to map styles to PDF tags
  for (var i = 0; i < csvRows.length; i++) {
    csvRow = csvRows[i].split(",");
    indesignStyle = csvRow[0];
    pdfTag = csvRow[1];
    for (var j = 0; j < paraStyles.length; j++) {
      if (paraStyles[j].name === indesignStyle) {
        style = doc.paragraphStyles.itemByName(paraStyles[j].name);
        //alert("Style  "+style.name);
        if (style.isValid) {
          //alert(style.isValid)
          style.styleExportTagMaps.add("PDF", pdfTag, "", "");
        }
        else {
            alert(error)
        }
      }
    }
  }
};
dialog.show();

I was able to get the required values to execute this line.

          style.styleExportTagMaps.add("PDF", pdfTag, "", "");

 But unable to update the tags when checking the Tag panel.
CSV Format :

Column1 | Column2
1hd     | H1
3hd     | H3
  

Can any helpme in this functionality.
