API. By using this new API, your app can use an instance of ConfirmationPrompt to display a prompt to the user, asking them to approve a short statement. This statement allows the app to reaffirm that the user would like to complete a sensitive transaction, such as making a payment.

The signature is produced by the trusted execution environment (TEE), which protects the display of the confirmation dialog as well as user input. The signature indicates, with very high confidence, that the user has seen the statement and has agreed to it.
