AUX switch (paired with RED 2-1) how to control the aux scene after I activated "Aux Switch Unique Scenes"

Ok, this should be simple but I cannot find what trigger visible in Hubitat does the AUX switch button create for me to have a separate behavior from the AUX switch. I activated “Aux Switch Unique Scenes” and activated the log to try to guess the answer but I don’t see the trigger even that I would react to from any Hubitat application.

So in short : Once I disconnect the AUX from the main switch using “Aux Switch Unique Scenes” how can I react to the AUX button in Hubitat
