Cannot convert value of type 'MKCoordinateRegion' to expected argument type 'Binding<MKCoordinateRegion>'

Question

I am new to SwiftUI and I'm trying to pass in some coordinates from an object I have inside a NavigationStack

I feel my approach is correct but the error suggests it needs a two way binding property which I don't have in this instance.

I tried setting a variable called var region and then passing that to the Map but I don't think I can use code in the middle of a View ?

What am I doing wrong?

struct ContentView: View {
    
    var chargingSessions: [ChargingSession] = [ChargingSession(id: 1, Name: "John", Kwh: 2.003, Price: 3.04, StartDate: Date.now.addingTimeInterval(-10000), Latitude: 59.9139, Longitude: 10.7522),
                                               ChargingSession(id: 2, Name: "Dave", Kwh: 4.003, Price: 6.04, StartDate: Date.now.addingTimeInterval(-1000000),Latitude: 59.9239, Longitude: 10.7622)]
    
    
    @State private var mapRegion = MKCoordinateRegion()

    let regionSize = 500.0
  
    
    var body: some View {
        
        
        TabView {
            
            Text("Home Screen")
                .tabItem {
                    Label("Home",systemImage: "house.fill")
                }
            
            
            NavigationStack {
                List(chargingSessions) { chargingSession in
