Hi Lucia,
in lesson 5 we introduced the new submission form below the video. You also find it in "course files" / worksheets (in the META-Pro 2022 tab all the way down, below the link to the course forum.)
Yes, this case study will count for your 5 required examples.
If it feels safe to share it in the forum I'm happy, otherwise you can email it to me. Anyhow I will review and comment it.
Thanks for asking!
