Text Alignment not Working

This code just format as currency on the fly a number while the user types (Brazilian format)

But I was not able to center the text in it.

What am I doing wrong?

import SwiftUI

struct Testes: View {
   @State var myText: String = ""
   var body: some View {
      HStack{
         CurrencyField(text: $myText, placeholder: "Valor")
      }
   }
}


struct CurrencyField: View {
   @Binding var text: String
   var placeholder: String
   var body: some View {
      HStack{
         TextField(placeholder, text: $text)
            .onChange(of: text, perform: { oldValue in
               text = formatCurrency(textoValor: oldValue)
            })
            .keyboardType(.decimalPad)
            .frame(width: 200, height: 40, alignment: .center)
      }
      .border(Color.black, width: 1)
   }

   
   func formatCurrency(textoValor: String) -> String {
      let numbers = textoValor.replacingOccurrences(of: "[^0-9]", with: "", options: .regularExpression)
      let n2 = Double(numbers) ?? 0
      let formatter = NumberFormatter()
      formatter.numberStyle = .decimal
      formatter.decimalSeparator = ","
      formatter.groupingSeparator = "."
      formatter.minimumFractionDigits = 2
      formatter.maximumFractionDigits = 2
      formatter.minimumIntegerDigits = 1
      formatter.locale = Locale(identifier: "pt_BR")
      return formatter.string(from: NSNumber(value: n2 / 100)) ?? "$0"
   }
}
