The session says that "when someone taps Add to Siri, the shortcut is added instantly, using your suggested invocation phrase". (at 21 min in Video)
Now we can see that new UI at iOS 15 beta 2. But on iPadOS 15 beta 2, it looks like unexpected behavior. It looks like INUIEditVoiceShortcutViewController shows in UISplitViewController, but we expect that in UIViewController itself.
And when we tap "Back" button, INUIEditVoiceShortcutViewController shows on left side of window.
It's Okay when the window has narrow width. This is what i expected.
Is there any way to implement "Add to Siri" feature or is it an iPadOS bug ?
