Hi,
Trying to set up real-time collaboration similar to this guide (but simpler). Using a custom image for which the Dockerfile looks like this:
from jupyter/minimal-notebook
run pip install --no-cache-dir jupyter-collaboration
Also tried mamba install.
In any case the module fails to load with this error (both in the cluster and if the container is run locally):
jupyter_collaboration | extension failed loading with message: AsyncLibraryNotFoundError('unknown async library, or not in async context')
Traceback (most recent call last):

Is anyone running it successfully?
