Model 3 rear sensor locations?

[Dinkum]

I have a small (3" diameter) metal logo that I wish to place on the rear of my car. I was thinking either side of my license plate but don't want to risk interference with any sensor. I have searched the web but cannot find the exact locatons of the rear sensors.

Is the immediate area on either side of the plate safe"

Thanks.

you can see the sensors in the bumper - small round circles

The ultrasonics (and the rear camera) are pretty obvious as noted... there's no other rear sensors (no radar or anything).
