Show / hide keyboard while in Immersive mode without Views / WindowGroups?

Most of the examples I have seen out there assume that, to enable or disable the keyboard in iOS / iPadOS / whatever OS that supports an on-screen keyboard, you must have some kind of View component available, which you will then modify to make the keyboard appear or disappear.

In fully immersive apps, however, we won't always have WindowGroups visible on screen, as the style of such UI elements would clash with the visual style of the immersive space being shown. Hence the question.

Is it possible at all?
