                                        .font(.system(size: 30))
                          
                            }.cornerRadius(60)
                           .frame(width: 400, height: 60)
                            
                        } .background(Capsule().fill(Color(red: 55/255, green: 66/255, blue: 114/255, opacity:1)))
                        .frame(width: 400, height: 60) //fin navigationlink
                        .buttonStyle(PlainButtonStyle())

I would like that the new window replace the older one:)

so I found this code

 import SwiftUI

    struct ContentView: View {
        @State private var show = false
        var body: some View {
            VStack{
                if !show {
                    RootView(show: $show)
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.blue)
                        .transition(AnyTransition.move(edge: .leading)).animation(.default)
                }
                if show {
                    NextView(show: $show)
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.green)
                        .transition(AnyTransition.move(edge: .trailing)).animation(.default)
                }
            }
        }
    }

    struct RootView: View {
        @Binding var show: Bool
        var body: some View {
            VStack{
                Button("Next") { self.show = true }
                Text("This is the first view")
            }
        }
    }
