How to set in Android to be navigated to the same fragment every time from the bottom navigation bar?

Question

I have 4 fragments: A, B, C and X.

A, B and C are found on the bottom navigation bar, so every time I click on item A, I get the A fragment on the screen, click on B, I get B.

When I click on C, I get the C fragment, which has a button, that takes me to X fragment. Now my problem is, that if I click on the Navigate to X button, after that when I navigate to anywhere from there and then back again on C, I get X.

But everytime I click on the item C, I want to get back to fragment C, no matter if I got to the X fragment before that. How can I implement this?

I found the answer, I needed to pop the X fragment off the stack, with adding this to the action tag navigating to it:

app:popUpTo='nav_graph_id'

and

app:popUpToInclusive="true"

@Antal Georgina is correct, Let me elaborate her answer, The app:popUpTo and app:popUpToInclusive attributes are essential when you want to clear fragments or destinations off the navigation stack in Jetpack Navigation.

Here’s a quick recap of what these attributes do:

app:popUpTo: Specifies the destination up to which you want to pop the back stack. The back stack will be cleared up to (but not including) this destination, unless app:popUpToInclusive is set to true.

app:popUpToInclusive="true": If set to true, the destination specified in app:popUpTo will also be removed from the back stack.

Example:

 <action
    android:id="@+id/action_to_fragmentY"
    app:destination="@id/fragmentY"
    app:popUpTo="@id/fragmentX"
    app:popUpToInclusive="true" />
