Sorry, I have no idea of how to inform VSCode of what's going on.

I believe the challenge is that map is registered dynamically via @Stream.register_api().

I've sometimes had success asking for help in the Pylance or Pyright github forums for questions like these. Those two tools are what typically powers VS Code.

But basically, if mypy can understand that .map is there. Then Pylance/ Pyright can too.
