_load_jupyter_server_extension function was not found error after Jupyter server upgrade

[ggarza31416]

Hello, I started to face this issue with nb_conda_kernels after I upgrade my jupyter-server from 1.24 to 2.14.0

[W 2024-12-12 17:40:41.413 ServerApp] nb_conda_kernels | extension failed loading with message: ExtensionLoadingError('_load_jupyter_server_extension function was not found.')
    Traceback (most recent call last):

This is my Jupyter environment

jupyter --version
Selected Jupyter core packages...
IPython : 8.22.2
ipykernel : 6.29.3
ipywidgets : 8.1.2
jupyter_client : 8.6.1
jupyter_core : 5.7.2
jupyter_server : 2.14.0
jupyterlab : 4.2.5

nbconvert : 7.16.3
nbformat : 5.10.4
notebook : 7.2.2
qtconsole : not installed
traitlets : 5.14.3

Does anyone know if nb_conda_kernels is not compatible with jupyter-server 2.x, or is this related to something else?
