Better way to raise number pad SwiftUI

Question

Upon navigating to a view, I want the number pad to already be raised. Right now I have a solution that works the first time (albeit with a delay) but fails to raise the number pad if the user navigates back a second time. Is there a better way to raise the number pad in SwiftUI (or to have it always up)?

Example Code:

struct ParentView: View {
    @FocusState var numberPadFocused: Bool
    @State var isActive: Bool = false
    var body: some View {
        NavigationView {
            VStack {
                Button {
                    numberPadFocused = true
                    isActive = true
                    print("Called")
                } label: {
                    Text("Navigate")
                }
            
                NavigationLink(destination: ChildView(focusState: $numberPadFocused), isActive: $isActive) { Color.white }
            }
        }
    }
}

struct ChildView: View {
    @State var text: String = ""
    @FocusState.Binding var focusState: Bool
    var body: some View {
        TextField("Enter Number...", text: $text)
            .keyboardType(.numberPad)
            .focused($focusState)
    
    }
}
