問題文
An app opens a modal from a message shortcut. When the modal is submitted, the handler needs to know which message the person started from. Where should that reference be carried?
選択肢
- In the block identifier of an input, which groups the entered values and names the state entry for the app.
- In the private metadata of the view, which comes back unchanged inside the submission payload for the handler.
- In the callback identifier of the view, which is fixed at design time and names the handler for the whole application.
- In the title text of the view, which is rendered to the person and read back from the display for the caller.
