Google Sheets Add row based on cell number value - google-apps-script

Question

I'm trying to make a google sheet script that adds a row based on cell value, basically if I have in the Quantity (Column D) 7x laptops, I want the script to add 6 additional rows below if Column H is marked as "Yes" through data validation.
What I was able to find and to do is only duplicate that row but is without data validation and I would prefer to add the data validation and possible make each quantity split to 1 (instead of 7) after the duplication.
`function autoDup() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var data = sheet.getDataRange().getValues();
var newData = [];
for(var n in data){
newData.push(data[n]);
if(!Number(data[n][3])){continue};// if column 3 is not a number then do nothing
for(var c=1 ; c < Number(data[n][3]) ; c++){ // start from 1 instead of 0 because we have already 1 copy
newData.push(data[n]);//store values
}
}
sheet.getRange(1,1,newData.length,newData[0].length).setValues(newData).sort({column: 1, ascending: false});// write new data to sheet, overwriting old data
}`
Hope someone is able to help me.
Thank you,

Column D contains a qty and goods description. If Column H = "Yes", you want to insert a number of rows below Col D equal to the qty minus one. If Column H <> "Yes, then take no action.
Sample data - Before
Sample data - After
function so5925663201() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetname = "59256632";
var sheet = ss.getSheetByName(sheetname);
var row = 7;
// get value of Column H
var colHValue = sheet.getRange(row,8).getValue();
if (colHValue === "Yes"){
//Logger.log("DEBUG: Col H = yes. do something")
// get value of Column D
var Value = sheet.getRange(row,4).getValue();
var searchterm = "x";
var indexOfFirst = Value.indexOf(searchterm);
//Logger.log("DEBUG: the first instance of 'x' is "+indexOfFirst);
// get the quantity and convert from a string to a number
var qty = Value.substring(0, indexOfFirst);
var qtynum = +qty;
// var newtype = typeof qtynum; // DEBUG
//Logger.log("DEBUG: the quantity is "+qtynum+", new type = "+newtype)
// This inserts rows after
sheet.insertRowsAfter(row, qtynum-1);
}
else{
//Logger.log("DEBUG: col H <> Yes. do nothing");
}
}
