That results in an array of various action names, and selects archery given that the default. Now we are able to use the chosen activity within our UI applying string interpolation – we are able to position the chosen variable directly inside strings.

So, add both of these modifiers on the internal VStack, telling SwiftUI to determine the whole team employing our id home, and animate its add and removing transitions by using a slide:
