docker – “Nbextensions” tab not showing in jupyterhub

can anyone explain how to fix or troubleshoot this issue ?
How i understand i already install packages and enable all modules.
There are no any issue(at least i can’t see any) with requirements or versions.
But after login in jupyterhub, the “Nbextensions” tab is not showing.

Output of commands jupyter --version , jupyter server extension list and jupyter nbextension list is printed below.

# jupyter --version

jupyter nbextension install --sys-prefix --py jupyter_nbextensions_configurator --overwrite
jupyter nbextension enable --sys-prefix --py jupyter_nbextensions_configurator 
jupyter serverextension enable --sys-prefix --py jupyter_nbextensions_configurator
