Description

Hey there - first off, thanks for making this plugin!

Feature request

State machines currently cannot be not invoked by websocket events

stepFunctions:
  stateMachines:
    myMachine:
      events:
        - websocket:
            route: $connect

Note: Full reproduction here

Initially I thought this was a bug (no error during deployment) but it looks like this just isn't supported currently.

Would be nice to have event feature parity with lambda functions 🤞

Research direction

Start with the linked example/serverless.yml reproduction, especially the state machine using the websocket $connect route. Trace how websocket events are handled for Lambda functions and determine the corresponding integration path for state machines. Done means the example deploys successfully and the websocket event invokes the configured state machine.
