Are iPad screenshots mandatory for an iPhone-only app submission?

Hi everyone, I want to confirm whether iPad screenshots are mandatory when submitting an app to the App Store. nshots required only when the app supports iPad, or must every iPhone app also provide them? Also, if the app can technically run on iPad but is not specifically designed for it, should I upload iPad screenshots or disable iPad support before submission? Any clarification from developers who have recently submitted an app would be helpful.
