Is there an auth option?

[kerolloz]

for example the JS client library has the auth option

const socket = io("ws://example.com/my-namespace", {
  auth: {
    token: "123"
  },
});

Yes, .setAuth( )
#177

socket = IO.io('https://api.$domain/token/',
  OptionBuilder()
  .setTransports(['websocket'])
  .setAuth({'token': token})
  .build()
  );
