Shelly Gen2 Scripting emitEvent

Hi there,

the new Shelly BLE Integration works great so I have seen they use Shelly.emitEvent to publish data to Homeassistant.

So I tried to build a script to use this event in HA for presence dedection. In the debug logs I‘ll se this notification but I don‘t know how to use this as Automation Trigger or entity value?

Maybe somebody knows how to access this values?
