When setting isAccessibilityElement to true, assistive tech like VoiceOver will stop looking for other accessible elements in that view hierarchy. So if we make a view accessible, its subviews, including buttons and labels won't be accessible.

What is the difference between isAccessibilityElement and accessibilityElementsHidden? The first one makes the view not accessible, but its subviews can still be accessible. The second one hides the view and all its subviews from assistive tech.
With the button trait VoiceOver will read “button” after the accessibility label and will indicate the user that, when focused, they can double tap anywhere on the screen to interact with it. UIButton has this trait by default.
