Mass Update of Multiple Saved Searches to change the owner

I have been researching for approximately a month on how to update multiple saved searches. I have been tasked with changing the owner of two terminated employees over to a different owner. Everything I have found states that I need to write a script. I have a script that is executing successfully, but not making the modifications in the script.

Can anyone provide any insight?

/**

 * @NApiVersion 2.x

 * @NScriptType ScheduledScript

 * @NModuleScope SameAccount

 */

define(['N/search', 'N/record'], function(search, record) {

  function execute(context) {

   var startDate = '1/01/2021 1:00 am'; // Specify the start date of the date range in yyyy-mm-dd format

   var endDate = '7/23/2023 11:00 pm'; // Specify the end date of the date range in yyyy-mm-dd format
