The values for these types also correspond to the [payment status types](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/34e17c3622637dbe8b02fac47b5c9b9ebf9e3596/src/Payments/PaymentResult.php#L21) from the [checkout endpoint response from the server](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/34e17c3622637dbe8b02fac47b5c9b9ebf9e3596/src/RestApi/StoreApi/Schemas/CheckoutSchema.php#L103-L113).
