How to disable BottomSheetDialogFragment dragging by finger?

I saw similar questions, but they\'re all about BottomSheet not BottomSheetD

Top rated answer contains boilerplate code such as Field and try-catches.

So here is a better version of it in Kotlin:

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    return super.onCreateDialog(savedInstanceState).apply {
        setOnShowListener(::onShow)
    }
}

private fun onShow(dialogInterface: DialogInterface) {
    val dialog = dialogInterface as BottomSheetDialog
    val frameLayout =
        dialog.findViewById(com.google.android.material.R.id.design_bottom_sheet)
            ?: return

    BottomSheetBehavior.from(frameLayout).apply {
        addBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
            override fun onStateChanged(bottomSheet: View, newState: Int) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING)
                    state = BottomSheetBehavior.STATE_EXPANDED
            }

            override fun onSlide(bottomSheet: View, slideOffset: Float) = Unit
        })
    }
}

Use it in BottomSheetDialogFragment
