I have a component A that should normally be displayed without a close button. However, when I open component A in a dialog, I want to add a Close Button to close the dialog.

How can I implement this behavior in Angular? Is there an elegant way to determine if the component is open in a dialog so I can add a Close Button accordingly?

Thanks in advance for your assistance!
