How to get user desktop notifications from a sudo-run systemd service on Wayland?

I'm running KDE Plasma on Nobara (Wayland), a Fedora-based distro. I'm brand new to Wayland and Nobara/Fedora, and have very limited experience with systemd. I have a bash script that sends a desktop notification with success, warning or error, depending on the outcome of the action. - When i run the script manually (not sudo), i get a desktop notification. - When i run the notification command in Terminal (not sudo), i get a desktop notification. - When i set up the /etc/systemd/system service, i do not get desktop notification, and i get an error in journalctl (the script otherwise runs fine): > Cannot autolaunch D-Bus without X11 $DISPLAY Example notification within the script: notify-send -a 'Successful!' -u low -i vcs-normal systemd service: [Unit] Description=Test Script Wants=network-online.target After=network-online.target [Service] Type=simple Nice=10 IOSchedulingClass=2 IOSchedulingPriority=7 ExecStart=/home/username/.local/bin/test.sh User=username Group=users My search indicates that the root-run systemd service doesn't have access to the user's desktop to put a notification. I saw an attempt around it , which was to add this to the service file: [Service] User=username Environment=DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/%U/bus In my case, it stopped the error in the journal, but it did not give me the desktop notification. I'm aware i can run systemd services as the user with systemd --user start test service files placed in ~/.config/systemd/user, and the notifications will work (i have managed to achieve that). But in this instance i would like to run this script as root. Thanks :)
