I build an app with SwiftUI and want to customized "About App" window, How can I achieve that ? I try the following way, but not works.      .commands {       CommandGroup(replacing: .appInfo) {         // Disable New Window, we don't need it.         Button(action: {           AboutView()         }, label: {           Text("About MyAPP")         })       }
