Leave session not working on beforeunload

OpenVidu v2 How to implement?
1

hi all,

I’m facing the currently issue: session.disconnect is not working on window event beforeunload. I’ve already tried using the openvidu tutorial code but still not working

useEffect(() => {
if (token) {
console.log(‘<<<마운트>>>’);
joinSession();
} else {
alert(‘로그인 후 이용 가능한 페이지입니다’);
navigate(‘/members/login’);
}

const handleBeforeUnload = () => {
  leaveSession(studyTime, mySessionId);
};

window.addEventListener('beforeunload', handleBeforeUnload);

return () => {
  console.log('언마운트');
  window.removeEventListener('beforeunload', handleBeforeUnload);
};

}, );

please help me!!
