I got this button now:

When it’s pressed, I want the ‘background’ to be removed, like this:

How would I do that? I can not get it to work. I am now adding the background by using a ZStack which is also not that nice because I need to initialize the Button twice.

This is a reproduction path:

import Foundation
import SwiftUI

struct TestButton<V: View>: View {
    @Environment(.colorScheme) var colorScheme: ColorScheme

    let content: V
    var foregroundStyle: Color? = nil

    var body: some View {
        ZStack {
            Button(action: {} ) {
                content
            }
            .padding(10)
            .background(Color(red: 0, green: 0, blue: 255/255))
            .applyDefaultCornerRadius()
            .offset(y: 5)

            Button(action: {}) {
                content
            }
            .padding(10)
            .background(Color.blue)
            .applyDefaultCornerRadius()
            .foregroundStyle(foregroundStyle ?? (colorScheme == .light ? Color.white : Color.black))
        }
    }
}

#Preview {
    TestButton(content: Text(verbatim: "Test"))
}
