How to change the way items in a list are move by the user (SwiftUI)

Question

I'm building a macOS app with a sidebar which has elements that the user can rearrange. I'm using .onMove() to detect when the user moves an elements and a function to move the item. Here is my code for that:

NavigationView {
    List() {
        ForEach(instances) { instance in
            NavigationLink(destination: InstanceView(instance: instance), tag: instance, selection: $selectedInstance) {
                InstanceRow(instance: instance).id(UUID())
            }
        }
        .onMove(perform: move)
    }
    .listStyle(SidebarListStyle())
    .navigationTitle("Instances")
    .frame(minWidth: 150)
    .toolbar {
        ToolbarItem {
            Button(action: toggleSidebar, label: {
                Image(systemName: "sidebar.left")
            })
        }
    }
    .onAppear {
        selectedInstance = instances[0]
    }
}

And the move() function:

private func move(from source: IndexSet, to destination: Int) {
    let previousSelectedInstanceIndex: Int = instances.firstIndex(of: selectedInstance!)!
    var revisedItems: [Instance] = instances.map{$0}
        
    revisedItems.move(fromOffsets: source, toOffset: destination )
        
    for reverseIndex in stride(from: revisedItems.count - 1, through: 0, by: -1) {
        revisedItems[reverseIndex].userOrder = Int16(reverseIndex)
    }
        
    do {
        try viewContext.save()
    } catch {
        // Error handling isn't finished yet
        let nsError = error as NSError
        fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
    }
    
    selectedInstance = instances[previousSelectedInstanceIndex]

}

Currently when I drag an item in the list, it shows a blue line where the item will end up when the user lets go. I was wondering how I could change this to act similar to how finder allows you to move items in the sidebar, where the other items animate around it when you drag it over them. I'm using swiftUI.

Thanks!
