Unifi Protect: is event_score (confidence level) for object (person, vehicle etc) detection still available?

Object detection is now indicated by binary_sensors for person, vehicle, package etc. and these work great.

There used to be a sensor entity (deprecated, now removed), which these replaced, e.g.

sensor.front_doorbell_detected_object

This included an attribute called event_score which was Protect’s ‘confidence’ level (out of 100) regarding this detection.

Is this still available anywhere? I don’t believe so but may have missed it.

If not, is it something that could return? Does Unifi Protect’s API still provide this information?

FYI, my use case is deciding whether to send a still photo of a vehicle to a numberplate recognition system, or not.
