Added the disabledExtensions option into the jupyter-lite.json to opt out two kernels in the UI but it doesn't work. about xeus-python-kernel

Thanks @JeongJun-Lee.

Where is the jupyter-lite.json file located?

Also note that you can also install jupyterlite-core instead of jupyterlite. jupyterlite-core comes with just the CLI without the Pyodide and JS kernels, that way it's not necessary to disable them via the config.

Sorry it works. But we need to refresh browser forcibly with draining cache in Crome development mode.
Is there any method to disable some extensions by any configuration without fixing a jupyter-lite.json in the _output folder manually when a build time?

@jtpio As you mentioned, first I tried to install jupyterlite-core only and then I tried a hosting on the localhost URL with 8000 port by the command, "jupyter lite serve", but there is same as before. All three kernels are shown on the UI.

I can show these logs when the building time:
