Ask HN: How to locate a stolen, turned off DJI drone?

I've recently been the victim of a theft, where they stole several things, including a DJI FPV drone. I have been unable to find a way to locate the drone - my understanding is that it has a transponder and that DJI should be able to know its location at all times, including when it's turned off. Anyone has any clue and could help?
