Why the font size of my navigationTitle is small?

Here is my code in visionOS 2.3

        NavigationSplitView {
            List {

            }
            .navigationTitle("Passwords")
        } detail: {
            Text("Hello")
                .navigationTitle("All")
        }

The font size of "Passwords" and "All" are smaller than the ones in Passwords app.

Would .navigationBarTitleDisplayMode(.large) work?
