Where is Supervisor?

Just installed Home Assistant OS on Raspberry Pi 4 following these instructions: Raspberry Pi - Home Assistant

HA OS spins up on Pi and I am able to get to it via http://homeassistant.local:8123/

But, my Home Assistant web interface sidebar does not include “Supervisor” option. What did I miss?

Home Assistant 2021.12.10

Update: Actually, “Supervisor” does show up under “Integrations”, but how do I add it to the menu?

Panel redirect is what you need setup to have any integration appears in side bar.

Thank you! Looks like exactly what I need at this point.
