Displaying a Deck instead of the GSlides on Dashboard

Hello,

I apologize if this has already been answered, I did search before asking. I recently downloaded a template and it had the google slides displayed in presentation mode. I cannot figure out how to do this as when I embed, it's just the entire google page where you can edit and see the menu bar. How do I embed the deck only? It doesn't look like there's anything special about the URL for the template.

Thank you
