Everyone sees whatever appears on your screen, including a message that pops up mid-call. Share one window rather than the whole screen whenever the option is there.
The drawing that proves the sentence above. It is the same card that is in the book.
Think of it as

Volume 1 has all 275 in fifteen chapters, with Staying Safe the largest chapter on purpose.
