How to get the segments and segment query from volumes for mesh?

Hi everyone,

I am working on constructing visualization links to view volumes in neuroglancer and im not sure how to get the segments and segments query part of the link to construct, here is the code your help is greatly appreciated

kwargs_default = defaultdict(lambda: None, kwargs)

    vol = CloudVolume(layer_path)

    return Layer(
        source=SourceClass(
            url=f'precomputed://{layer_path.split("file://")[-1]}'
            if data_url_prefix is None
            else f'precomputed://{data_url_prefix}{layer_path.split("precomputed_volumes/")[-1]}'
        ),
        type=TypeEnum(vol.layer_type),
        tab=Tab("source"),
        name=f"{vol.layer}",
        cross_section_render_scale=kwargs_default["cross_section_render_scale"],
        visible=kwargs_default["visible"],
        shader_controls=kwargs_default["shader_controls"],
        pick=kwargs_default["pick"],
        selected_alpha=kwargs_default["selected_alpha"],
        object_alpha=kwargs_default["object_alpha"],
        base_segment_coloring=kwargs_default["base_segment_coloring"],
        mesh_silhouette_rendering=kwargs_default["mesh_silhouette_rendering"],
        mesh_render_scale=kwargs_default["mesh_render_scale"],
        segments=kwargs_default["segments"],
        segment_query=kwargs_default["segment_query"],
        color_seed=kwargs_default["color_seed"],
        segment_default_color=kwargs_default["segment_default_color"],
        saturation=kwargs_default["saturation"],
        skeleton_rendering=kwargs_default["skeleton_rendering"],
    )

Hi! I think this would be a more appropriate question for the neuroglancer repo. I'm not familiar with the Neuroglancer Python API.
