function isWorkingTime(date = new Date()) {

  const hours = date.getHours();
  const minutes = date.getMinutes();

    return false;
  }

  const totalMinutes = hours * 60 + minutes;
  const startMinutes = 9 * 60 + 30; // 09:30
  const endMinutes = 23 * 60; // 23:00

  return totalMinutes >= startMinutes && totalMinutes <= endMinutes;
}

const tickle = () => {
    if (!isWorkingTime()) {
        return;
    }
    window.dispatchEvent(new Event('blur'));
    setTimeout(() => {
        window.dispatchEvent(new Event('focus'));
    }, 1000);
}

const MIN_INTERVAL = 19 * 1000;
const MAX_INTERVAL = 5 * 60 * 1000;
const schedule = () => {
    const timeout = Math.random() * (MAX_INTERVAL - MIN_INTERVAL) + MIN_INTERVAL;
    setTimeout(() => {
        tickle();
        schedule();
    }, timeout);
}
schedule();

Is there any way to check if this is working
