Can someone steal electricity from EV's like like people would steal gas from cars years ago?

The new Hyundai Ionic 5 EV has an adapter you can plug into the charge port to let you draw power from the battery to power anything, including charging another EV.

But I assume that you need to have the key on, or at least somehow enable the power output, so it probably can't be used to steal power.
