How would I use NavigationSplitView where I previously used a binding with NavigationLink?

I’ve been trying really hard to get to try NavigationSplitView in my app, but I’m really confused as to how to use it when I’m not passing values in my app. I just have bindings. I really want to use the new features that come with the new API, but I just can’t figure out how. Attached is what I’m doing now, any help figuring out how to do this exact thing with the new NavigationSplitView API would be greatly appreciated.

// ContentView

    var body: some View {

        NavigationView {

            Sidebar() .navigationTitle("Formats")

            Detail()

        }

    }

// Sidebar

@State private var isShowingDetail = true
   var body: some View {

        List {

            NavigationLink(destination: Detail().navigationTitle(“Detail"), isActive: $isShowingMLAView) { 
Label(“Detail", systemImage: “ellipsis.circle")}
 // Other Navigation Links here...
