There are two events for windows Activated and Deactivated

Activated - https://learn.microsoft.com/en-us/dotnet/api/system.windows.window.activated?view=net-5.0

Deactivate - https://learn.microsoft.com/en-us/dotnet/api/system.windows.window.deactivated?view=net-5.0

when mainwindow is out of focus Deactivated event is triggered, here set that popup.IsOpen to false and once mainwindow is focused Activated event is triggered set Popup.IsOpen to true.

Example:

Private Popup myPopup;
public Constructor()
{
      myPopup = new Popup();

      TextBlock textContent = new TextBlock();
      textContent.Text = "Here is my Code";

      myPopup.Child =  textContent; 

      System.Windows.Application.Current.MainWindow.Activated += ActivatePopupWindow;
      System.Windows.Application.Current.MainWindow.Deactivated += DeActivatePopupWindow;
}

 private void DeActivatePopupWindow(object sender, EventArgs e)
 {
      myPopup.IsOpen = false;     
 }

 private void ActivatePopupWindow(object sender, EventArgs e)
 {
      myPopup.IsOpen = true;      
 }

You can build your window to have an Expander in a place where you like it (for instance under the picture). The expander itself will be the button that will open this extra section containing your infos.

   <Expander>
        <Grid ...>
            <Grid.RowDefinitions>
                ....
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                ...
            </Grid.ColumnDefinitions>
            //put your content here
        </Grid>
    </Expander>

you can use also set the TemplateProperty of the expander to attach to it some animation when it opens.

The expander is a control that "hide" a portion of your window until it's toggled and you can place inside it anything you want. You don't need the popup unless it's really what you want
