How can I create listeners, emit custom events and react to those ?

[MetriciRO]

Hello.
I am looking to create custom events so that I don't need to keep running the same routines/functions over and over again insidevoid loop(){}, practically making my code synchronously.
Is it possible to do something like this: https://github.com/esp32m/events but using the Arduino ESP32 Core: https://github.com/espressif/arduino-esp32 ?

I have a big project on an ESP32 with multiple modules, like reading a Wiegand Card, controlling some inputs, some buzzers, some LEDs, relays, etc.
I don't need these routines/functions running all the time. I would like to set up some listeners so that I can emit events when a Wiegand Card is read, or when there is a signal on an Input and only react then.
