How to disable BottomSheetDialogFragment dragging by finger?

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

This is the Kotlin version of azizbekian's answer since someone asked about using data binding

@SuppressLint("RestrictedApi")
override fun setupDialog(d: Dialog?, style: Int) {
    super.setupDialog(d, style)
    dialogExampleBinding = DataBindingUtil
        .inflate(LayoutInflater.from(context), R.layout.dialogExample, null, false) //This is for data binding only
    d?.setContentView(R.layout.dialogExample)

    val myDialog:BottomSheetDialog = d as BottomSheetDialog
    val dField = myDialog.javaClass.getDeclaredField("behavior") //This is the correct name of the variable in the BottomSheetDialog class
    dField.isAccessible = true
    val behavior = dField.get(d) as BottomSheetBehavior<*>
    behavior.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
        override fun onStateChanged(bottomSheet: View, newState: Int) {
            if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                behavior.state = BottomSheetBehavior.STATE_EXPANDED
            }
        }

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