Kotlin 为什么 Dialog 没有 NavController [Missing]

I am trying to use the latest update of Nav Component in my application

where i can add dialog(BottomSheetDialogFragment) in my nav graph

nav_version = "2.1.0-alpha05"

Part of code from my nav_graph:

    <dialog
        android:id="@+id/settingFragment"
        android:name="com.andor.navigate.notepad.listing.fragment.SettingFragment"
        tools:layout="@layout/fragment_setting">
        <action
            android:id="@+id/action_settingFragment_to_confirmationFragment"
            app:destination="@id/confirmationFragment" />
    </dialog>
    <dialog
        android:id="@+id/confirmationFragment"
        android:name="com.andor.navigate.notepad.ConfirmationFragment"
        tools:layout="@layout/fragment_confirmation" />

In my Setting's Fragment i have a button(logout_btn) to trigger the action: action_settingFragment_to_confirmationFragment

设置片段的OnActivityCreated中的代码:

    logout_btn.setOnClickListener {
       Navigation.findNavController(view!!).navigate(R.id.action_settingFragment_to_confirmationFragment)
    } 

When i Click on the button there is a runtime Exception:

java.lang.IllegalStateException:视图 androidx.constraintlayout.widget.ConstraintLayout{550ae09 V.E.. .1，1-719,526}没有设置NavController 在androidx.navigation.Navigation.findNavController(Navigation.java:84) 在com.andor.navigate.notepad.listing.fragment.SettingFragment$onActivityCreated$2.onClick(SettingFragment.kt:56) 在android.view.View.performClick(View.java:7352) 在android.view.View.performClickInternal(View.java:7318) 在android.view.View.access$3200(View.java:846) 在android.view.View$PerformClick.run(View.java:27800) 在android.os.Handler.handleCallback(Handler.java:873) 在android.os.Handler.dispatchMessage(Handler.java:99) 在android.os.Looper.loop(Looper.java:214) 在android.app.ActivityThread.main(ActivityThread.java:7045) at java.lang.refect.Method.Invoke(本机方法) 在com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493) 在com.android.internal.os.ZygoteInit.main(ZygoteInit.java:965)

My aim is to open a dialog from another dialog, but for some reason my dialog is not having(missing) NavController.
