How to Get the Pacing Guides Over the Screens

Is there a way to add these headers to a custom made activity? I noticed that this activity was editable and the headers (pacing) was copy and pasted into my customization, but I can’t seem to find how it is being created.

Thanks for any help!

I believe this is something that only the official Desmos curriculum lessons include and is not (currently) something that regular authors can accomplish.
