Hello! I have a question about merch artist apps: specifically about the bullet point that says: "Merch artists are expected to design charms, stickers, enamel pins, prints, recipe cards, digital icons, and phone backgrounds," do I need to have all of those things included in my portfolio in order to be considered?

Also for the same bullet point, do I need to have a specific item in my portfolio in order to pitch an idea for it? Ex: can I pitch an idea for a phone bg without having one in my portfolio?
