Animation gRPC stub in animation missing?

[fygy10]

Looking at the docs, animation is using a gRPC API. In the 'animation.py' file, the stub is being imported via:

import stability_sdk.interfaces.gooseai.generation.generation_pb2 as generation

Going down tot he 'Animator' class and the 'render' method, i don't see the stub being used.

This might be naive question, but how is the gRPC API working for animation if there is no stub being implemented in the animation?
