Does @microsoft/signalr support react-native?

Describe the bug

I'm trying to connect to signalr service from my react-native app using the @microsoft/signalr npm package v8.0.7

new HubConnectionBuilder()
      .withUrl('wss://my_signalr_service', {
        transport: HttpTransportType.WebSockets,
        skipNegotiation: true,
      })
      .withAutomaticReconnect()
      .configureLogging(LogLevel.Debug)
      .build()

I've got the error from the _resolveUrl method of the HttpConnection class:

Cannot resolve wss://my_signalr_service

In the call stack I've found this line:

if (!Utils_1.Platform.isBrowser) {
    throw new Error(`Cannot resolve '${url}'.`);
}

So, it looks like React Native is not supported at all?

Expected Behavior

@microsoft/signalr connects to a service url from react-native app or it throws the explicit error that provides more information.

I found the issue in HttpConnection.js.

The _resolveUrl method can't work with url that starts with wss in react native. But in browser it works fine. I think, the behaviour in browser and in react native should be the same to reuse one code base, for instance.
