Callback on door unlocked (neither opened, nor closed/locked)

Hi all, went through several similar topics, neither of them was dated earlier than 2020, so I wonder if there’ve been improvements in the API set for the bridge.
I have set up a callback to call a shelly via an HTTP GET request. I need it to trigger only when my Nuki SmartLock gets unlocked (via app/auto-unlock), but it actually triggers everytime I open the door, every time I close the door and also every time I lock the SmartLock.
I have the door sensor, SmartLock v 2.15.3 - Bridge v 2.17.0

How can I make the callback to run ONLY when I unlock the SmartLock?
