I just moved from 3.6.7 to Jupyterlab 4.* , in the process of creating our docker image for the JupyterHub.
I see this error/warning now:
jupyter labextension disable "@jupyterlab/apputils-extension:announcements"
Config option `kernel_spec_manager_class` not recognized by `DisableLabExtensionsApp`.
[W 2024-03-18 22:08:47.683 LabApp] Config option `kernel_spec_manager_class` not recognized by `LabApp`.
Anything I should do about this?
