Jupyterhub 1.3.0 - toggle menu by default

Hello :slight_smile:
How can I disable by default the menu bar (Header and Toolbar)?

Reading on the internet they say to set up a custom.js file where to set some code, but I can’t find the file (I don’t have this folder “~ / .jupyter /”)

Solved: Found it in a docker path:
javascript: /var/lib/docker/overlay2/86a3a74e69c2a66f431fb6050e5cc7b1a57a4b4cface1aeb21b697878be15ddd/diff/opt/conda/lib/python3.8/site-packages/notebook/static/custom/custom.js
css: /var/lib/docker/overlay2/86a3a74e69c2a66f431fb6050e5cc7b1a57a4b4cface1aeb21b697878be15ddd/diff/opt/conda/lib/python3.8/site-packages/notebook/static/custom/custom.css
