[Question] matrix sharing feature

[Kinasa0096]

Can someone explain what this "matrix" thing is during startup, and whether I need it?

[ComfyUI-Manager] The matrix sharing feature has been disabled because the `matrix-nio` dependency is not installed.
        To use this feature, please run the following command:
        D:\ComfyUI\.venv\Scripts\python.exe -m pip install matrix-nio
