Make NavigationView searchable but only for one page in the TabView – Ios swift

I have a NaviagtionView with a TabView and 4 TabItems inside. One of the TabItems should display a searchbar. I can make the NavigationView .searchable but I only want that inside the on TabItem where I want to do the search. How can i do that?
Here is my code:

var body: some View {
    NavigationView {
        
        TabView{
            HomeScreen()
                .background(Color("BackgroundColor"))
                .tabItem{
                    Image(systemName: "house")
                }
            PostScreen()
                .background(Color("BackgroundColor"))
                .tabItem{
                    Image(systemName: "plus")
                }
            SearchScreen()
                .background(Color("BackgroundColor"))
                .tabItem{
                    Image(systemName: "magnifyingglass")
                }
            ProfileScreen()
                .background(Color("BackgroundColor"))
                .tabItem{
                    Image(systemName: "person")
                }
        }
        .navigationTitle("MyApp")
        .navigationBarTitleDisplayMode(.inline)
       .searchable(text: $text)
        
        
    }
}

    Found a way, add an extension:

    extension View {
    @ViewBuilder func `if`<Content: View>(_ condition: Bool, transform: (Self) -> Content)
        -> some View
    {
        if condition {
            transform(self)
        } else {
            self
        }
    }
}

    and then use it like this:

    .if(selectedTab == "search") { view in
    view.searchable(text: $search)
}

    searchable work with single child view after NavigationView. So my modification is to remove the parent NavigationView and add NavigationView in the individual View.
