How do I make sure that multiple Google Sheets files in a folder are protected in one go?

Question

I have a working code that allows me to protect multiple Google Sheets files located inside a folder and to add editors.

But, I have to run the code multiple times in accordance to the number of files in the folder. For example: If I have seven files in the folder, I have to run it seven times.

How do I make sure the files are protected with one run?

This is my humble attempt of putting together the code:

function AddEditorsProtection(){
var myFolder = DriveApp.getFoldersByName('Folder Name').next(); //Add Folder name
var spreadSheets = myFolder.getFilesByType("application/vnd.google-apps.spreadsheet"); 
while (spreadSheets.hasNext()) // Loops through all Spread Sheets inside the folder.

var sheet = spreadSheets.next();
var name = sheet.getName();

var spreadsheet = SpreadsheetApp.openById(sheet.getId());
var firstSheet = spreadsheet.getSheets()[0];
var secondSheet = spreadsheet.getSheets()[1];
var thirdSheet = spreadsheet.getSheets()[2];

spreadsheet.setActiveSheet(firstSheet);
var protection = firstSheet.protect().setDescription('Description 1');
protection.addEditors(['Editor 1 Email', 'Editor 2 Email']); // Insert list of editors.

spreadsheet.setActiveSheet(secondSheet);
var protection = secondSheet.protect().setDescription('Description 2');
protection.addEditors(['Editor 1 Email', 'Editor 2 Email']); // Insert list of editors.

spreadsheet.setActiveSheet(thirdSheet);
var protection = thirdSheet.protect().setDescription('Description 3');
protection.removeEditors(['Editor 1 Email', 'Editor 2 Email']); // Insert list of editors.
};
