Installable onEdit Trigger when Sheet is copied having to be run Manually First

Question

I have sheet that I have been working on that has an installable onEdit trigger, that works as it should. But my issue is that when I copy the sheet you have to go into App Scripts and run the create trigger to set the authorization. I have as you'll see in the code below tried to install a menu item that would allow the user to run the create trigger without going into the project. I would really like to find a way if at all possible to get around the authorization each time the file is copied. The users will be creating several copies throughout the day so I am trying to make this as easy as possible for the end user. I am open to any suggestions on getting this to run smoothly.

    var ui = SpreadsheetApp.getUi()
    var spreadSheet = SpreadsheetApp.getActiveSpreadsheet();
    var ssID = spreadSheet.getId();
    var ssName = spreadSheet.getName();
    var s1 = spreadSheet.getSheetByName('Sheet1');
    var tp = spreadSheet.getSheetByName('Time Pivot');
    var qa = spreadSheet.getSheetByName('QA Pivot');
    var lastRow = s1.getLastRow();
    var lastColumn = s1.getLastColumn();
    var cell = spreadSheet.getSheets()[0].getRange('A2');

    function onOpen() {

      tp.getRange('G1').setValue('StartTime');
      tp.getRange('G2').setValue(new Date());

      ui.createMenu('TSB Stuff')
        .addItem('Do Me First', 'createEditTrigger')
        .addSeparator()
        .addSubMenu(ui.createMenu('Scan Type')
          .addItem('Scan A IMEI', 'scanAImei')
          .addItem('Scan A SIM', 'scanASim')
          .addItem('Scan B IMEI', 'scanBImei')
          .addItem('Scan B SIM', 'scanBSim')

    function createEditTrigger() {

          var modelCell = c.offset(0, 4);
          var invTypeCell = c.offset(0, 6);
          var returnValues = getModelInvType(String(c.getValue()));
          var modelInfo = returnValues.toString().split(',');
          var f2Value = s1.getRange('F2').getValue();
          var f = c.offset(0, 5)
          var cpRange = s1.getRange('H2:J2');
          var psRange = s1.getRange(row, 8, 1);
          cpRange.copyTo(psRange);
          modelCell.setValue(modelInfo[0]);
          invTypeCell.setValue(modelInfo[1]);
          timeCell.setValue(new Date());
          f.setValue(f2Value);
        }
      }
    }

    function getModelInvType(c) {

      const userPwd = '*************';
      const output = []
      const conn = Jdbc.getCloudSqlConnection(dbUrl, user, userPwd);
      const stmt = conn.prepareStatement('SELECT Model,idInvType FROM ProductDetail WHERE Serial = ?');
      stmt.setString(1, c);
      const resultSet = stmt.executeQuery();
      const numCols = resultSet.getMetaData().getColumnCount();
      while (resultSet.next()) {
        tmpCols = numCols;
        const row = [];
        while (tmpCols--) row.push(resultSet.getString(numCols - tmpCols));
        output.push(row)
      }
      stmt.close();
      resultSet.close();
      return output; //return output
