Here is my code:

let socket = io(`https://${url}`);
const peerServer = new Peer(undefined, {
    host: url,
    secure: true,
    port: '443',
    path: '/peerjs',
    config: {
      debug: 3,
      iceServers: [
        {urls: ['stun:stun1.l.google.com:19302']},
        {
          username: 'epz-hBZGVrdW5sZTE=',
          credential: 'c531d3-a2e6-0242a140004',
          credentialType: 'password',
          urls: [
            'turn:us-turn4.xirsys.com:80?transport=udp',
            'turn:us-turn4.xirsys.com:3478?transport=udp',
            'turn:us-turn4.xirsys.com:80?transport=tcp',
            'turn:us-turn4.xirsys.com:3478?transport=tcp',
            'turns:us-turn4.xirsys.com:443?transport=tcp',
            'turns:us-turn4.xirsys.com:5349?transport=tcp',
          ],
        },
      ],
    },
  });

            peerServer.on('open', (userId: any) => {
              let roomId = '7b22dc91-3638-4964-95f2-d32b61541b66';
              socket.emit('join-room', roomId, userId);
            });

            socket.on('user-connected', (localPeer: any) => {
              const call = peerServer.call(localPeer, stream);
              call.on('stream', (audioStream: any) => {
                setStreams([...streams, audioStream]);
              });
            });

            peerServer.on('call', (call: any) => {
              call.answer(stream);
              call.on('stream', (userStream: any) => {
                setUserStreams([...userStreams, userStream]);
              });
            });
