Is your feature request related to a problem?

Can't use the WebSocket feature because my WebSocket endpoint requires authentication with AWS Signature.

Describe the solution you'd like

Ideally, the "Authorization" tab that is available when defining HTTP requests will simply be made available when defining WebSocket connections as well, and the auth settings simply applied to the initial HTTP handshake request.

Describe alternatives you've considered

No response

Additional context

Postman has great support for signing HTTP requests with AWS Signature. However, this feature is not supported for WebSocket connections.

WebSocket APIs built with AWS may require authentication using AWS Signature. It works exactly as in a REST API request, and is used to sign the initial HTTP request sent by the client to initiate the handshake for creating a new WebSocket connection.

Using the command line tool wscat and custom scripts, I have tested this successfully with the signature in the request URL, and verified it works as desired, allowing only connections that are properly signed and authenticated.
