Can't get CDEmu Service

Hello I’m trying to get GCDEmu working.

I’ve added the following to my configuration based on the docs:

programs.cdemu.enable = true;
programs.cdemu.gue = true;

When I try to run GCDemu I get the following error:

Daemon autostart error
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name net.sf.cdemu.CDEmuDaemon was not provided by any .service file (2)

When I “nixos-option services” I do not see a cdemu service listed. Nor when I “systemctl list-units --type=service”.

If I explicitly add cdemu-daemon as a package it does not make the service available.

What additional configuration am I missing?
