Who would need to press the power button to actually turn off or restart the device, right?
The setting to change this is also pretty much buried under Settings -> Special Features -> Gestures.
(Yes, I have no idea why the Assistant is in German when the phone is set to English either 🫠)
My post literally says so :D It’s still a dickhead move to put the assistant in there as the default when setting up the device and hiding the option under “Gestures”.
