How can an admin stay logged in in Opencart?

Question

opencart

In opencart 3, the admin remains logged in for a short time, logged in as admin, subjectively half an hour passed, he logged out.
In ocstore 2.3 - the same.
And in ocstore 3, for example, it lasts forever until you log out yourself.

Is there any way to make the logged in admin in Opencart 3 and Ocstore 2.3 also last continuously?
If anyone has done this and knows, then please write.

in common.js admin add

function serverPing() {
      $.ajax({ url: location.href });      // <--  добавить  до  2
   }
$(document).ready(function() {       // <-- найти эту строку   1

   setInterval('serverPing()', 30000);    // <-- добавить после   3

log in and don't close the tab
