IR Remote Control with Argon One and Harmony Elite

[Lusayalumino]

I've got an Argon One V2 Case (with built-in infrared) with Raspberry Pi 4B. I'm trying to use a Logitech Harmony Elite remote to control some basic functions in Moode (play, pause, next track).

I've Successfully loaded Argon One's IR scripts in SSH (argonone-ir).

Articles I've read recommend adding one of the following "Devices" to the Harmony Remote:
- Microsoft Kodi
- Raspberry Pi 4
- Flirc Kodi

Nothing I have done seems to yield any results; does anyone have any wisdom?

If this isn't possible, is it possible to remote control Moode over IP? (the Logitech Harmony Hub can control IP devices)
