Home Assistant Supervisor

Hello,

I m new in home assistant. I want to install home assistant in a raspberryPi that runs BalenaOs.
I read the instructions (https://www.balena.io/blog/monitor-air-quality-around-your-home-with-home-assistant-and-balena/) and runs ok, but the supervison missing. How can i add the supervisor too?

Thank you very much

Did you get any solution to this? I’m having the same problem.
