* ALLOWED_ORIGINS=http://localhost:3000,http://localhost:4000 
*/
const ws = new WebSocket(`http://localhost:3000/ws?room=${room}&accessToken=$${accessToken}`);

ws.addEventListener("open", () => {
  console.log("New Client Connected")
  ws.Send("Hello, World")
})

ws.addEventListener("message", (package) => {
  let messages = package.data.split("\n");
  console.log("Messages", messages)
