How to add a separator to a PopupBox?

[andrewducker]

When adding multiple items to a PopupBox, how do I add a separator between groups of them?

@andrewducker adding a separator between the PopupBoxs content is like adding a separator to any other Panel.Children.
This xaml:

<materialDesign:PopupBox Style="{StaticResource MaterialDesignPopupBox}">
  <StackPanel>
    <Button Content="Button 1" />
    <Separator/>
    <Button Content="Button 2" />
    <Separator/>
    <Button Content="Button 3" />
  </StackPanel>
</materialDesign:PopupBox>

gets you the following result:
