Maybe swiping up from the input field could also work, instead of the long press?

Hey Liam, thanks for your thoughts. I agree swiping up also works and actually that’s my next step on the prototype. I’m not worried about discoverability, as it can be solved with in product communication. The only thing I didn’t want to do is eat up on precious real estate around input field by adding some extra buttons (mine is the simplest possible, but imagine stickers/photos/emojis there)
