Start tvOS SideBar Menu Collapsed

I'm trying to make the side bar menu on my tvOS app have the same behavior of Apple's tvOS App. I would like to have the side menu collapsed at the cold start of the app. I'm trying to achieve this by using the defaultFocus view modifier, which should make the button inside the TabView focused at the start of the app. But no matter what I do, the side bar always steels the focus from the inside button.

struct ContentView: View {
    enum Tabs {
        case viewA
        case viewB
    }

    enum ScreenElements {
        case button
        case tab
    }

    @FocusState private var focusedElement: ScreenElements?
    @State private var selectedTab: Tabs? = nil

    var body: some View {
        Group {
            TabView(selection: $selectedTab) {
                Tab("View A", image: "square", value: .viewA) {
                    Button("View A Button", action: {})
                        .frame(maxWidth: .infinity, alignment: .center)
                        .focused($focusedElement, equals: .button)
                }
            }
            .tabViewStyle(.sidebarAdaptable)
            .focused($focusedElement, equals: .tab)
        }
        .defaultFocus($focusedElement, .button, priority: .userInitiated)
    }
}

Is there a way to start the side bar menu collapsed at the start up of the app?
