Hey, @[email protected]. I was trying to find a way to customize what showed up in the Stream for microblog, when I found this code:

try:
    from data.stream import (  # type: ignore  # noqa: F401, E501
        custom_stream_visibility_callback,
    )

    stream_visibility_callback = custom_stream_visibility_callback

It looks like there is supposed to be a way to customize it by writing this custom_stream_visibility_callback.

I think what I'm supposed to do is create a file at data/stream.py, and basically put the function in there, modeling it after the default_stream_visibility_callback in app/customization.py.

Am I understanding that correctly? I couldn't find any mention of this in the docs.
