Hello. I have closed installation of Home Assistant Supervised (in VirtualBox). I understand I can only install grafana plugins from the list that is directly in grafana/plugins.
I would like to install plugin manually from github and istructions say " 1. Copy the contents of “Grafana_Status_panel” to the “/var/lib/grafana/plugins” folder". I think I cannot access that folder because terminal add-on in Home Assistant can only access HA environment and not that which belong to add-ons.
So how to install garafana plugin that needs to be downloaded?
