Nbextensions tab not appearing on dashboard when using docker and jupyter notebook image

[pdubz-sudo]

I'm using a jupyter notebook image in a docker container and I don't get a nbextension tab in the dashboard after I refresh the page. The extensions are working though when I do a jupyter subcommand such as

jupyter nbextension enable codefolding/main

I run the docker with this command in my terminal
docker run --rm -p 8888:8888 -v /Users/me/Desktop/project:/home/jovyan/ jupyter/tensorflow-notebook

I open the jupyter notebook and run these in a cell
!pip install jupyter_contrib_nbextensions
!jupyter contrib nbextension install --user
!pip install jupyter_nbextensions_configurator
!jupyter nbextensions_configurator enable --user

I refresh the home page but the tab never appears. Am I missing something?

[gothicVI]

pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
pip install jupyter_nbextensions_configurator
jupyter nbextensions_configurator enable --user

These commands are meant to be run from the command line.
It could be that a running notebook session locks some files they would alter. I'd thus not recommend running them from within a notebook.

Thanks for the reply. Yes, I was able to resolve this by placing the commands in the dockerfile instead.
