Facial recognition - batt. doorbell

I just bought the video doorbell along a homebase 2 (which I guess is newer and better than a homebase 1).
In the settings in the app, under smart detection, it says my doorbell supports facial recognition … how do I set that up ?

It does not support facial recognition, it supports facial detection.

Ah… Yes I see now… Darn…

Facial Recognition would be a cool feature
