Dismissing WebView with custom navigation bar

Question

I have this code:

ForEach(news){ item in
                NavigationLink {
                    WebView(url: URL(string: item.url)!)
                        .navigationOverride(title: .latestNewsTitle) {
                            presentationMode.wrappedValue.dismiss()
                        }
                } label: {
                    LatestNewsListItemView(item: item, geo: geo)
                        .padding([.leading, .trailing])
                }
            }

When cell is clicked, WebView is opened. I wanted to edit WebView navigation bar, so I made this code (I also added this as modifier on WebView in code above).

func navigationOverride(title: String, actionBack: @escaping () -> Void) -> some View {
    
    navigationBarBackButtonHidden(true)
        .navigationBarItems(
            leading: Button(action: actionBack) {
                Image(systemName: "chevron.backward")
                    .frame(width: 50, alignment: .leading)
                    .offset(x: 20)
                
                Text(title)
                    .commonFont(.semiBold, style: .title1)
            }
                .foregroundColor(Color.black)
        )
}

And this is WebView

struct WebView: UIViewRepresentable {

let url: URL
var webview: WKWebView?

func makeUIView(context: Context) -> WKWebView {
    return WKWebView()
}

func updateUIView(_ webView: WKWebView, context: Context) {
    let request = URLRequest(url: url)
    webView.load(request)
}
}

Image and Text in WebView are shown, but the problem is when Button is pressed, it doesnt dismiss WebView.
