[Support]: Built-in LPR

[xavan83]

Describe the problem you are having

Using 0.16, I am trying to test LPR detection.
I add lpr enable true in the config file (not sure if I need to also add that config directly to the camera).
I see that some files are downloaded during first frigate startup.
My Frigate+ model is detecting license plates and I receive boxes containing license plates in mqtt messages.
However, Frigate+ does not add a sublabel in the car object containing the detected plate.
How can I add some logs in frigate to see if everything is correctly setup?
