## Returns

`Promise` will be returned which resolves with a `Response` object upon a successful confirmation. `false` will be returned when user flow is cancelled in such a case that a user closes the popup modal.

If the confirmation fails, the `Promise` will resolve with an {error} object that describes the failure.

`Promise<Response | false>`
