You have disabled the extension in your current environment, not in jupyter-lite
runtime environment. I think you need to use runtime config file jupyter-lite.json to define disabledExtensions
. A config like:
{
"jupyter-lite-schema-version": 0,
"jupyter-config-data": {
"disabledExtensions": ["@jupyterlab/launcher-extension"]
}
}
should work. This is my guess, I am entirely sure though!
