BottomSheetDialogFragment setting look beyond and other behaviors

Question

I want the bottom screen to drop in and then rise in full screen when it slides up. I'm currently showing when I press "Button 1" because I cannot get peek to work.

I can, however, move it up so that it occupies the entire screen. Ideally, this will be done automatically.

When I move it back, it completely lowers.

I need the following behavior:

• The bottom sheet should drop in 300dpor whatever, at any time.

• Slipping on the bottom sheet should lead to the fact that it displays a full screen, as in the second figure.

• A shift down the bottom sheet should return to its peeking height.
