my first post so apologies for any wrong links and format.

I found a very useful piece of script in the link below, and specifically in the code text. It works great for single import ranges, but I need to have multiple sheets linked in the Const donorID and in the Const URL. Is this possible?

Is sO, please assist with a sample modified script.

How to allow access for importrange function via apps script?

 function addImportrangePermission() {
  // id of the spreadsheet to add permission to import
  const ssId = SpreadsheetApp.getActiveSpreadsheet().getId();

  // donor or source spreadsheet id, you should get it somewhere
  const donorId = '1GrELZHlEKu_QbBVqv...';

  // adding permission by fetching this url
  const url = `https://docs.google.com/spreadsheets/d/${ssId}/externaldata/addimportrangepermissions?donorDocId=${donorId}`;

  const token = ScriptApp.getOAuthToken();

  const params = {
    method: 'post',
    headers: {
      Authorization: 'Bearer ' + token,
    },
    muteHttpExceptions: true
  };
  
  UrlFetchApp.fetch(url, params);
}
