Google apps script Exceeded maximum execution time

I try to adapt my code to avoid the time limitation but it looks like it is not working. Can someone help me with that? what am I doing wrong? It is running but not avoiding the time limitation problem. The main function is a function that extracts many calendars from google calendar and does some easy calculation. I receive a time limit restriction, for now, my solution was to create 8 codes and trigger them every hour, but I feel it is not super clean and we could do better. Thanks a lot, j.

function update_main_master() {
  var sheet2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Id Calendriers - Dates Debut et Fin"); //Sheet name where you will have the loop
  sheet2.getRange('d1').setValue(0);
  // Set filters
 
  var begin = new Date(); // Time when execution begins
  // Your code before loop
  export_gcal_to_gsheetLast1()
   // Your code before loop
  
  
  
  var x = sheet2.getRange('D1').getValue(); // Retrieve x stored in previous execution (from PropertiesService? Spreadsheet?) (should be 0 if first execution)
  var timeLimit = 1000 * 60 * 1; // 4 minutes (in milliseconds)
  while (new Date() - begin < timeLimit) { // Check if 5 minutes passed since execution start
    for (var x = 0; x < xngData.length && xngData[x][3] != undefined; x++) {
      
      // Your code inside loop
  export_gcal_to_gsheetLast1()
    // Your code inside loop
    }
  }
  // Store current x index (using PropertiesService? Or write to the spreadsheet itself?
  var ContorlSS = SpreadsheetApp.openById('IDssdfsadfsafd');
  var ContorlSh = ContorlSS.getSheetByName('Id Calendriers - Dates Debut et Fin');
  ContorlSh.getRange('e1').setValue('Updated');
  ContorlSh.getRange('f1').setValue(new Date());
  ContorlSh.getRange('d1').setValue(x);
  if (x < xngData.length) { // Create trigger if x hasn't reach the total number of iteration
    ScriptApp.newTrigger("update_main_master")
    .timeBased()
    .after(1000 * 20) // This fires the function 1 minute after the current execution ends. Change this time according to your preferences
    .create();  
  }
}
