How to hide the image icon in the selector preview but show it with the selector open (Swiftui)

Question

How to hide the image icon in the selector preview but show it with the selector open?

Actual code

Picker("method", selection $method) {
  Label {
    Text("cash")
  } icon: {
    Image(systemName: "dollarsign.circle.fill")
  }.tag(cash)
}.pickerStyle(.menu).frame(maxWidth: .infinity, alignment: .trailing)

I read the documentation but not found any solutions https://developer.apple.com/documentation/swiftui/picker
