Can't Focus Text Box MacOS SwiftUI

Hi,

I am trying to focus a textbox once a button is clicked, and I am not sure how to do this?

Present TextField

 @State var isHidden: Bool = true
...
if !isHidden {
        withAnimation{
          TextField("Add Note...", text: $textValue)
            .padding(.top, 10.0)
             
        }
        .transition(.move(edge: .trailing))
        .textFieldStyle(RoundedBorderTextFieldStyle())
                 
}

Button to show Text Field

if (buttonCount == 0){
        isHidden = false
        buttonCount += 1
}

At the moment everything works fine but when I click the button to show the textfield its not auto-selected by default.

MacOS Version: > 11.0
