Xiaomi Binding developer key missing (after migration to OH3)


Unforutinetally I didn’t make OH2.5 backup as I thought that my z-wave heaters don’t get recognized and upgrading OH3 was just a lucky shot before reinstalling it again.

Upgrade worked but I can’t see the Xiaomi key anywhere (I did purge the openhab2 installation).
The Aquara sensors that I have are working - is there any chance that the key is somewhere in the files?

Before playing with adb on the phone, I just wanted to ask - maybe there is a way to find it somewhere.
