Private BLE Device & Samsung SmartTag

Hi
The documentation for the new Private BLE is saying it needs the IRK of a BLE device.

I got and applied the IRK code for my Samsung phone no problem using this guide via one of my home’s M5Atom Espresence. Pretty straightforward to do as long as it’s on a later release (I used V3.2.4)

When I head out I sometimes leave my phone behind, so what would be better in my case is getting the IRK from the SamsungSmarttag on my keys.
I never leave home without them, so that would be much more accurate method of defining my home/not_home status.

Anyone know how to get the IRK on the smarttag as it can’t pair with the ESP32 the same way I did with the phone?
