The building blocks of an App are what we refer to as Elements
Elements are two-way interactive components such as Polls, Predictions or Trivia questions which have a range of configuration fields and typically have two-way behaviour that allows them to count up votes or responses from users.
Elements are created, triggered, scheduled and managed in the Timeline view. They can be pre-created, cloned, edited in real-time and revoked from the Timeline.
Note that every App has a different set of Elements; the developer of the App decides which Elements to use and which to hide. There is no such thing as a 'standard' set of Elements.
