Notification not shown

[floli]

Hello,
I am running system-bridge 5.4.0 at Arch Linux as root using the systemd unit file from the home page.

With the HA integration, stuff like system information, battery, etc. is shown just fine.

Sending a notification using the action

action: notify.system_bridge_osiris
data:
  message: foo

does not show any notification. The log message is

Jan 29 21:37:21 osiris dbus-daemon[33142]: [session uid=0 pid=33140 pidfd=5] Activating service name='org.freedesktop.Notifications' requested by ':1.0' (uid=0 pid=33113 comm="/usr/bin/system-bridge backend")

system-bridge client notification as user works, bot not as root.

Should system-bridge be run as user with systemd?

Thanks!
