Using DialogFragment as one of the Fragment in Android NavController

Question

I have a graph defined using XML and I added a DialogFragment as one of the Fragment in my NavGraph. when I call NavController.navigate with resId and bundle on that nav controller I don't see any Dialog being displayed. Is there any way I can use DialogFragment instead of standard Fragment?

<fragment
        android:id="@+id/noLoginDialog"
        android:name="com.ram.view.NoLoginDialog"
        android:label="NoLoginDialog">
        <argument
            android:name="argTitle"
            android:defaultValue="null"
            app:type="string"/>
        <argument
            android:name="argBody"
            android:defaultValue="null"
            app:type="string"/>
        <argument
            android:name="argButton"
            android:defaultValue="null"
            app:type="string"/>
    </fragment> 

and my action is defined as below

 <container_fragment
        android:id="@+id/homeFragment"
        android:name="com.ram.home.HomeFragment"
        android:label="HomeFragment">

        <action
            android:id="@+id/action_homeFragment_to_noAuthAlertDialog"
            app:destination="@id/noLoginDialog"/>
    </container_fragment>

My other actions with activity and fragments works just fine.

hum, Navigation Library will never open an Fragment as Dialog, it just replace the first (home destination) to other destination in your NavHostFragment.

Google said:

A destination is any place you can navigate to in your app. While destinations are usually Fragments representing specific screens..

Please provide more information, like your navigation code (java/kotlin).
