I'm fairly new with scripts and Virtual Switches in Domoticz and can't figure this one out by myself

Online I've found a script (Python) to control my Ziggo Mediabox and would love to integrate this feature in my Domoticz Setup
LINK: https://github.com/Xorfor/Domoticz-ZiggoHorizon-Plugin
When searching on the forums I have found someone suggesting this script but sadly without any explanation about how to.
I searched all over this forum and Google but sadly nothing that can help me so that's why I am writing this now
I hope someone can help me with this, it would be greatly appreciated!\
Greetings,
Branco
