ToC option not showing after installing nbextensions configurator

[ehsong]

I have anaconda so I ran

conda install -c conda-forge jupyter_nbextensions_configurator

However after installing when I go into nbextensions tab I don't have the table of contents option -- how do I make this option visible in jupyter notebook?
