Create a Chips Dropdown in Google Sheet using Apps Script

Question

I have an Apps Script code that dynamically creates a dropdown depending on another one, but the generated dropdown has no chips:

Is there any way I can customize the dropdown style within Apps Script?

The code is the following:

function onEdit() {
  var monthTabs = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];

  var aCell = SpreadsheetApp.getActiveSheet().getActiveCell();
  var aColumn = aCell.getColumn();

  if (aColumn == 4 && monthTabs.includes(SpreadsheetApp.getActiveSheet().getName())) {
    var cellContent = aCell.getValue();
    var range = SpreadsheetApp.getActiveSheet().getRange(aCell.getRow(), aColumn + 1);

    if (cellContent == "") {
      range.clearDataValidations();
    }
    else {
      var sourceRange = SpreadsheetApp.getActiveSpreadsheet().getRangeByName(cellContent);
      var rule = SpreadsheetApp.newDataValidation().requireValueInRange(sourceRange, true).build();
      range.setDataValidation(rule);
    }
  }
}

Currently, there's no way to customize the datavalidation dropdown style using Google apps script or Google sheets api. You may request this feature here
