Show a button to continue to another view

You would've thought this is basic stuff, I have a view with CancelButtonView with the following code:

import SwiftUI

struct CancelButtonView: View {
  var body: some View {
    NavigationView {
      NavigationLink(destination: AboutView()) {
        Button {
           
        } label: {
          HStack {
            Spacer()
            Text("Continue anyway")
              .foregroundColor(.white)
              .padding(.vertical, 10)
              .font(.system(size: 14, weight: .semibold))
            Spacer()
          }.background(Color.blue)
        }
      }
    }
  }
}

struct CancelButtonView_Previews: PreviewProvider {
  static var previews: some View {
    CancelButtonView()
  }
}

in my other view I am calling this:

CancelButtonView()

Why can't I see my button?!
