Problem installing Adguardhome-go

I installed Adguardhome-go from entware and it works well.
However it won’t start automatically unless it’s installed as system service.
I ran the install script and this is the output:

> CoreELEC:~ # AdGuardHome -s install 2024/10/20 23:25:50 [info] AdGuard Home, version 2024/10/20 23:25:50 [info] service: control action: install 2024/10/20 23:25:50 [fatal] service: executing action "install": Failed to install AdGuard Home service: open /etc/systemd/system/AdGuardHome.service: no such file or directory

You will have to supply service yourself and put it in /storage/.config/system.d and enable it.

Thanks. Where can i find the systemd files to manually put there?
