Subscribing to the Channel

Once the connection is established, you can send a subscription request to the server, requesting to subscribe to a specific channel (e.g., UserBalanceChannel).

socket.onopen = function() {
  socket.send(JSON.stringify({
    command: 'subscribe',
    identifier: JSON.stringify({
      channel: 'UserBalanceChannel'
    }),
  }));
};

After successfully subscribing, you will receive a confirmation message

{
  "identifier": "{"channel":"UserBalanceChannel"}",
  "type": "confirm_subscription"
}

This message confirms that you have successfully subscribed to the UserBalanceChannel and are now receiving updates.
