title: Get the view which was dismissed and from which the current view is display
body: <p>I have a <code>NavigationView</code> which is showing a different view via <code>fullScreenCover</code> when I press a Button. Now I need to know when my view from where I pressed the Button is getting visible again and what was the view before. In the view shown by the <code>fullScreenCover</code> im using <code>@Environment(\.dismiss) var dismiss</code> to dismiss it.</p>
  <p>So here is my concrete use case:</p>
  <ul>
  <li>I have my main screen with two Buttons A and B.</li>
  <li>A is showing sub view 1 and B is showing sub view 2.</li>
  <li>When I dismiss one of these sub screens I need to know if I was in A view 1 or 2 before.</li>
  </ul>
  <p>Is this somehow possible?</p>
