Question about Nuki Smart Lock Pro (4th Gen) CH cylinder

There is an adapter for Kaba locks.
However, you have to remove the large door knob

Yes, we bought it more than a year ago, as I was unsure whether the adapter was included, I also bought it from Galaxus Nuki door knob adapter DORMA, KABA

We were able to unscrew the door knob and then it worked perfectly with the adapter.
Unfortunately, I no longer know whether the adapter for the door knob was even included in the Nuki scope of delivery.
