ios – Cannot see the again button in Navigation View

For some motive I am unable to see the again button within the Navigation View.

I do not know if there’s some additional code that I want so as to add within the baby view however I do not know. I kind of copied the code from the tutorial, however I am unable to see the again button within the baby view.

    var physique: some View {
        VStack {
            //Rectangle 12
            Rectangle()
                .fill(Shade(#colorLiteral(purple: 0.7137255072593689, inexperienced: 0.10196077823638916, blue: 0.10196077823638916, alpha: 1)))
                .body(width: .infinity, peak: 50)
                .padding(.backside, 0.0)
            
            
            NavigationView {
                ZStack{
                    Shade(purple: 0.9, inexperienced: 0.9, blue: 0.9).edgesIgnoringSafeArea(.all)
                    
                    
                    ScrollView(.vertical, showsIndicators: true) {
                        
                        HStack{
                            Textual content("Market").font(.customized("Arial", dimension: 35))
                                .fontWeight(.medium)
                                .foregroundColor(Shade(purple: 0.1, inexperienced: 0.1, blue: 0.1))
                                .padding(EdgeInsets(prime: 15, main: 20, backside: -2, trailing: 0))

                            Spacer()
                        }
                
                        ForEach(produitsdfsdf, id: .id ) { product in
                            
                            NavigationLink(vacation spot: TempView()) {
                                LandingPresets.listItem(title: product.title, description: product.value, charge: product.class)
                            }
                        }
                        
                    }
                    .navigationBarHidden(true)
                    
                }
            }
            .padding(.prime, -8.0)
            
            
        }.ignoresSafeArea(edges: .prime)
            .onAppear {
                ProductAPI().getAllProducts {(productArr) in
                    self.produitsdfsdf = productArr
                }
            }
        
        
    }
