The links on Configuration.yaml - Home Assistant don’t work on my system. There is no menu item to install add-ons, like File Editor. In Profile Advanced Mode is active. There is no difference between active/ not-active. Version HA 2022.11.3. On RPi 4 with Raspberry Pi OS Lite (64-bit). HA and DeConz in Docker-containers.
What kind of installation are you using? Add-ons are only available for supervised and HAOS installs. If you did not use that installation mechanism, then you wont have addons - and therefore the link:
Won’t work…
You’ll ahve to mfigure out something else to edit your configuration.yaml
