I study on JavaScript, create an online game. I have a problem: it is necessary to remove the player from the room (by closing the tab, by closing the browser, by going to another page); I try to use the beforeunload and unload events, but I can't track it. Share your experience, there may be another way to remove a player from a room?

addEventListener('unload', (event) => {
    /**
     * Send notify of your absence in room.
     */
    $.post("/ajax/player/remove", {
        userID: window.user.id,
        roomID: window.room.id
    });
});
