ValueError: "@kaggle/jupyterlab" is not a valid npm package

Hi,

I found your extension through this article: https://www.kaggle.com/product-feedback/117903.

By launching jupyter labextension install @kaggle/jupyterlab, I was not able to install this jupyterlab extension, I get the error: ValueError: "@kaggle/jupyterlab" is not a valid npm package.

This was the full error log:

I saw that the above nodejs version was rather low though, so I deinstalled it and installed nodejs from the conda-forge channel, but then again got the same error.
Full log of that:

I also can't find the extension when I browse manually through the extension tab on the left on JupyterLab's GUI, nor can I find your package manually in the npm package repository (https://www.npmjs.com/search?q=kaggle).
Could it be that this extension has been discontinued? It looked like a nice idea to me though.

Kind regards.
