Why doesn't node.js (socket.io) save user data?

Question

JavaScript

Hello.
I am using socket.io and only need to send messages to 1 user inside a large room.
I have a room connection event. In it, I write the new user to the users object.

socket.on("connect to room", data => {
        logger.info("Начал присоеденяться к комнате ", socket.id);
        users.push({
            audioOff: false,
            videoOff: false,
            id: socket.id,
            roomId: data.roomId,
            socket: socket,
            username: data.username,
            avatar: data.avatar
        });
        logger.info("Добавился в список пользователей", socket.id);
    })

Sometimes, when I connect to 1 and the same socket in different browser windows, I see that the array of users is not complete. Another user is missing. They seem to use different arrays of users.
How can I make it so that users can get a list of all users connected to a socket?
I don't quite understand where user data is stored.
