Add Timestamp to Update Tab onEdit of Main Tab

Question

I would like to have it that when a row is edited that it only copies the name, phone and adds a timestamp of the edit on another tab in Google Sheets. Each row on Update sheet should be a new row from edit.

function onEdit(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName('Main');
  var date  = new Date();
  var rowIdx = sheet.getActiveRange().getRowIndex();
  var rowValues = sheet.getRange(rowIdx,1,1,sheet.getLastRow()).getValues();
  Logger.log(rowValues);
  var destValues = [];
  destValues.push(rowValues[0][0]);// copy data from col A to col A
  destValues.push(rowValues[0][2]);// copy data from col C to col B
  destValues.push(rowValues[0][1]);// copy data from col B to col C
  destValues.push(rowValues[0][3]);// copy data from col D to col D

  var dest = SpreadsheetApp.getActive().getSheetByName('Updates');
  dest.getRange(dest.getLastRow()+1,1,1,destValues.length).setValues([destValues]);



}

The above is working but i cannot figure out how to get the timestamp to show.

The outcome should display the roadname, phone and then C:C should have timestamp of change made.

I have updated the below sheet to show expected outcome

Expected outcome of 2nd Tab

Roadname	Phone	Timestamp
Edit 1	555-5555	2/16/2023 09:14:52
edit 2	555-5555	2/16/2023 09:14:52
Edit 3	555-5555	2/16/2023 09:14:52
Edit 4	555-5555	2/16/2023 09:14:52

Data Table:

Road Name	Date Contacted	Phone number	Clan Name	State	Status	Comment
Name2	2/1/23	5551212222				Some Comment 1
Name1	2/1/23	5551212222				Some comment 2
Name4	2/1/23	5551212222				Called him

Try something like this:

/**
* Simple trigger that runs each time the user manually edits the spreadsheet.
*
* @param {Object} e The onEdit() event object.
*/
function onEdit(e) {
  if (!e) {
    throw new Error('Please do not run the onEdit(e) function in the script editor window.');
  }
  let sheet;
  if (e.range.columnStart !== 7 || !(sheet = e.range.getSheet()).getName().match(/^(Main)$/i)) {
    return;
  }
  const rowValues = sheet.getRange(e.range.rowStart, 1, 1, sheet.getLastRow()).getValues().flat();
  const destValues = [0, 2].map(index => rowValues[index]).concat([new Date()]);
  e.source.getSheetByName('Updates').appendRow(destValues);
}
