I'm a bit of a pi hacker, and while I'm clever with HATs and software, I'd like to detect when an appliance (a garage heater I installed) turns on and off. I started researching current sensing units, and ultimately purchased this one:

The heater I installed is 220V and runs at 21A max. I have access to the supply wires as I installed it myself, and there's room the base of the heater for me to install this sensor, or something similar. When I discovered this sensor, in my mind it 'worked' - so I ordered it. Now that I have it in my hands, I am not sure about how to move forward with this project. I see other current sensing questions posted here, but I guess I'm looking for a specific example of how to employ a device like this connected (somehow) to GPIO and perform these detections.
Can anyone give me a link to an example project using one of these and how it's done? Or some helpful hints here? Thanks!
