Android Navigation Component popupTo self

Question

I'm using Navigation Component to navigate in my app. I'm working with tree structure and I'm navigating users node by node -> Node == NodeFragment. But now I'm struggling with back navigation to particular node.

E.g.: Image navigation stack with look like this A -> B -> C -> D when user wants to navigate from node D directly to node B I want to popup fragment C, D and go directly to B?

E.g.: You can imagine something like navigating trough folder structure where you are navigation the same fragment again and again. And then you want to go back to particular folder which is not parent of the current one.

But I don't know ho to achieve it with Navigation Component. For navigation I'm using self action. Thanks in advance.

<fragment
    android:id="@+id/nodeFragment"
    android:name="com.example.NodeFragment">

    <action
        android:id="@+id/action_chatbotBuilderChildrenFragment_self2"
        app:destination="@id/nodeFragment" />
        
</fragment>

Answer 1

Go into your navigation graph, click on the action (the arrow line) on C -> D, on the right panel (make sure in design mode instead of split or code mode) you will see pop up tp option, then choose Fragment B, that's it. So whenever you are in Fragment D and you click the Back key, the app will nagivate back to Fragment B.
