Beep boop! Here is a Binder link where you can try out this change.

Looks like CI is failing because of a dependency in distributed, but looks like the dask + distributed versions are pinned in https://github.com/dask/dask-tutorial/blob/main/binder/environment.yml so not sure why:

ModuleNotFoundError                       Traceback (most recent call last)

    164 try:
--> 165     from cryptography import x509
    166     from cryptography.hazmat.backends import default_backend

ModuleNotFoundError: No module named 'cryptography'

During handling of the above exception, another exception occurred:

This looks great thanks. I'm not too worries about the CI failures given this is just a text change.

Thanks @jacobtomlinson!
