accessing uri params for websockets api (question)

How to access uri query string parameters for websockets API with chalice?

E.g. my gateway uri has extra paramet(s) like
wss://my-example-gateway.com/api/?**id=some-id**&**param=value**

In nodejs I'd access the id and param values using event.queryStringParameters like in the code below:
exports.handler = async (event) => {
id = event.queryStringParameters.id,
param = event.queryStringParameters.param,
// ... do other stuff
};

but in chalice on_ws_connect event argument (type WebsocketEvent) I only see
```
self.domain_name = request_context['domainName']
self.stage = request_context['stage']
self.connection_id = request_context['connectionId']
self.body = event_dict.get('body')
```

Start by tracing the WebsocketEvent construction used by on_ws_connect and inspect the event dictionary fields currently exposed, including body and request_context. Compare this with the API Gateway event shape described in the question and determine what behavior is needed for query-string access. Done means the supported access pattern is clear and covered by an appropriate test.
