The lesson
Demo a new agent through the smallest familiar action in your real UI, so the workflow reads as something viewers already know.
The shot is a dark GitHub issue list with the Assign menu open, headed "Assign up to 10 people to this issue". Copilot appears in the list under peckjon, tagged "Your AI pair programmer", and the cursor is on its checkbox.
Don't copy the exact UI sequence if your product has no existing ritual to attach to. Keep the idea of starting from the viewer's most familiar action.
