Not sure why we had this disabled.
This is for the nmcli/nmtui `agent` subcommand [0]
which allows it to act as a polkit agent.
> nmcli agent { secret | polkit | all }
> Run nmcli as a NetworkManager secret agent, or polkit agent.
For example, this is useful if you want to use nmcli/nmtui to authenti-
cate with polkit on a headless server.
