android - RecyclerView Scrolling not work proper with BottomSheetDialogFragment

Question

I added one UserListFragment inside BottomSheetDialogFragment all looks good data is displayed in list but problem is RecyclerView content not scroll properly. Below my code is given

 val sheet = ListBottomSheetFragment()
                sheet.show(supportFragmentManager,"tag_bsdf")

BottomSheetDialogFragment

class ListBottomSheetFragment : BottomSheetDialogFragment() {
private var behaviour: BottomSheetBehavior<*>? = null

val bottomSheetCallback = object : BottomSheetBehavior.BottomSheetCallback() {
    override fun onSlide(bottomSheet: View, slideOffset: Float) {

    }

    override fun onStateChanged(bottomSheet: View, newState: Int) {
        if (newState == BottomSheetBehavior.STATE_HIDDEN) {
            dialog?.dismiss()
        }
    }

}

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val d: BottomSheetDialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog

    d.setOnShowListener {
        val d = dialog as BottomSheetDialog

        val bottomSheet: FrameLayout? = d.findViewById<View>(com.google.android.material.R.id.design_bottom_sheet) as FrameLayout?
      
       
        bottomSheet?.let {
            behaviour = BottomSheetBehavior.from<View?>(bottomSheet)
            behaviour?.addBottomSheetCallback(bottomSheetCallback)
            behaviour?.state = BottomSheetBehavior.STATE_EXPANDED
        }
    }
    return d;
}

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    return inflater.inflate(R.layout.fragment_bottom_sheet_dialog, container, false)
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
   switchFragment(UserListFragment(),"tag_user_list")

}

private fun switchFragment(fragment: Fragment, tag: String) {
    val transaction = childFragmentManager.beginTransaction()
        transaction.add(R.id.container, fragment, tag)
    transaction.commit()
 
}

companion object {
    fun newInstance(): ListBottomSheetFragment {
        return ListBottomSheetFragment()
    }
}
