What type of HA did you install docker/haos?
4th last row: https://www.home-assistant.io/installation/#compare-installation-methods
You have chosen an installation method marked with 
for addons.
I installed it with docker on raspberry pi.
Looking at this table, I am very grateful to know that the addon
does not appear because I installed it with Docker.
I’ll have to figure out how to install it as Supervised.
thank you
Supervised is a trap. It is the most restricted install method. You would be better off running HAOS in a VM.
