The lesson
Demonstrate a presentation product by running the demo as a presentation, with a real workflow slide on screen.
One yellow slide is titled 'What's changed since last round' with three numbered items, 'Updated card styling', 'Horizontal carousel scrolling' and 'Updated button styling', beside a phone showing a 'Hi Chef' app. A slide counter below reads '3 of 4'. The film ends on 'Figma Slides, now in beta.'
Only works when your product is the format the film is made in, so don't force it for a non-visual tool. Keep a realistic work scenario, with an ordinary review slide, as demo content.
