Confirmation dialog object

Adds a confirmation step to an interactive element: before the action reaches your app, the reader sees a dialog and must confirm it.


Used in	Button element, Checkboxes element, Date picker element, Datetime picker element, Multi-select menu element, Overflow menu element, Radio button group element, Select menu element, Time picker element, Workflow button element

Usage

Set it as the element’s confirm field. If the reader cancels, nothing is sent to your app and a select, date, checkbox or radio choice goes back to what it was.
