Google Apps Script: Temporarily run script as another user

Question

I have a Google Spreadsheet containing a number of sheets, each or which I have protected using the \"Except certain cells\' routine in order to protect shared users from editin

The most viable option is to have a web App to insert the row where desired. You can pass the sheet Name and row No via a get or post method. The below method uses a get method. Your google script would look something like this:

function insertRow() {
  var ss = SpreadsheetApp.getActive()
  var sheetName = ss.getActiveSheet().getName()
  var row = ss.getActiveRange().getRow()
  // Below URL is the link to  web App, you will generate it by publish >Deploy as web app. Code for Web app is below. 
  var url ="Put the generated URL here"
  var queryString = "?sheetName="+sheetName+"&rowNo="+row
  url = url + queryString
  Logger.log(url)
  var request = UrlFetchApp.fetch(url)
  if (request != 'Success')
    Browser.msgBox("Sorry Unable to insertRow")
}

Next, you will deploy a web App which will process the get request and add new rows to the sheet. The code would look like this:

function doGet(e) {
  var SheetID = "Your Sheet ID here"
  var param = e.queryString
  var parameters = param.split("&")
  // This just checks only 2 parameters are present else gives a invalid link
  if (param != null && parameters.length == 2){
    param = e.parameter
    var name = param.sheetName
    var row = Number(param.rowNo)
    } else {
    return ContentService.createTextOutput("Failed")
    }
  try{  
     var ss = SpreadsheetApp.openById(sheetID)  
     var sheet = ss.getSheetByName(name)
     sheet.insertRowAfter(row)
     sheet.getRange(row + 1,1).setValue("Inserted Row")
     }
     catch (err){
      return ContentService.createTextOutput("Failed")
     }
 return ContentService.createTextOutput("Success")
}

Make sure to run the webApp once to give it authorization/permission to edit your google sheets. Since the webApp will run under your authorization, it would be able to insert Row without an issue of permission. Also, you can add a unique ID(Email ID of the effective User?) to the get request to make sure only valid request from within the google sheets scripts is processed.
