Hiding tabs/sheets in Google Spreadsheet from certain users

问题

I am aware of the protect sheet/range function in google spreadsheet but what I want to do is to hide sheets completely from certain users. I have found an answer to this with the code below. I am able to hide certain tabs/sheets to the specified user automatically upon opening the spreadsheet but that doesn't stop them from unhiding the tabs/sheets again. Any recommendations to restrict them from unhiding those tabs?

function onOpen() {
  var adminUsers = ['sample@google.com'];
  var Users = ['sample@gmail.com'];

  if (adminUsers.indexOf(Session.getEffectiveUser().getEmail()) >= 0) {
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SETTINGS').showSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('INSTRUCTION').showSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('EMPLOYEES').showSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('LEAVE').showSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('TEAM DASHBOARD').showSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('EMS').showSheet();
  }

  if (Users.indexOf(Session.getEffectiveUser().getEmail()) >= 0) {
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SETTINGS').hideSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('EMPLOYEES').hideSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('LEAVE').hideSheet();
    SpreadsheetApp.getActiveSpreadsheet().getSheetByName('EMS').hideSheet();

    }
}

Viewers can't make any change to Google Sheet spreadsheets. In order to prevent that a viewer make a copy to get access to hidden sheets and rows, block the spreadsheet to be printed/copied/downloaded. For details see Stop, limit, or change sharing.

It's worth to note that hiding or showing a sheet will make it effective to all users who are viewing the spreadsheet.
