0.15.0 beta 5 (config?) : where do I specify the tracked objects to be shown in the explore window?

[ElectronicBattle]

How do I get a list of car number plates (licence plates?)

The magnifying glass icon shows me thumbnails of

Dog (363 Tracked Objects)
Person (300 Tracked Objects)
Fox (226 Tracked Objects)
Car (47 Tracked Objects)

but not licence_plate

My config says

objects:
      track:
        - face
        - person
        - cat
        - dog
        - bird
        - deer
        - fox 
        - badger # placeholder
        - car
        - license_plate

and also

objects:
  filters:
...
    license_plate:
      min_score: .6
    amazon:
      min_score: .75
...

https://docs.frigate.video/configuration/objects/ doesn't show licence_plate, but nether does it show fox but fox is shown in the explore view.

I've been through the config and the documents as best I can but I am struggling to find the right bit. please can you help?

License plate is just an attribute of car. If a license plate is detected it will be used to choose the best image for each car.

OK - I can conceive that that is a good way to try to guarantee that the "car" image chosen is the one with the most readable licence plate.

(I see that, in the explore window, searching for "licence" works well at showing all images with a reasonable view of licence plates).
