addEventListener to no action?

I would like a modal to pop up if there has been no action on the page by the user for the last 3 seconds. Is there a way for addEventListener to run a function upon no action for 3 seconds?

Use setTimeout() to open the modal after 3 seconds and use an event listener for key presses (or key up, etc) to reset the timeout.

let timeout = undefined;

function resetTimer() {
  if (timeout) {
    clearTimeout(timeout);
  }

  timeout = setTimeout(function() {
    // open modal, call resetTimer() when it is closed to restart the check...
    /*
       modal.onClose = resetTimer;
       modal.open();
    */
    console.log('open modal');
  }, 3000);
}

window.onload = function() {
  // every time a key is pressed reset the timer
  document.addEventListener('keypress', resetTimer);
  // start the timer
  resetTimer();
};
