CORS settings for SocketIOServer?

[Smoodi]

Hey,
I am trying to mimic a socket io server written in JS.
Ever since the SocketIO protocol v3 CORS (Cross-Origin-Resource-Sharing) is disabled by default (see https://socket.io/docs/v4/handling-cors/).
I have looked into the SocketIOServerOption class where I would have assumed a parameter to be set but can't I can't find any setting for it.
Does the SocketIOSharp implementation have any settings that could be modified so that CORS can be enabled or configured?

Kind regards
