-    /**
-     * Enrolls a user's face for a remote client, for example Android Auto.
-     *
-     * The HAL implementation is responsible for creating a secure communication
-     * channel and receiving the enrollment images from a mobile device with
-     * face authentication hardware.
-     *
-     * Note that the Hardware Authentication Token must be valid for the
-     * duration of enrollment and thus should be explicitly invalidated by a
-     * call to revokeChallenge() when enrollment is complete, to reduce the
-     * window of opportunity to re-use the challenge and HAT. For example,
-     * Settings calls generateChallenge() once to allow the user to enroll one
-     * or more faces or toggle secure settings without having to re-enter the
-     * PIN/pattern/password. Once the user completes the operation, Settings
-     * invokes revokeChallenge() to close the transaction. If the HAT is expired,
-     * the implementation must invoke onError with UNABLE_TO_PROCESS.
-     *
-     * Requirements for using this API:
-     * - Mobile devices MUST NOT delegate enrollment to another device by calling
-     * this API. This feature is intended only to allow enrollment on devices
-     * where it is impossible to enroll locally on the device.
-     * - The path MUST be protected by a secret key with rollback protection.
-     * - Synchronizing between devices MUST be accomplished by having both
-     * devices agree on a secret PIN entered by the user (similar to BT
-     * pairing procedure) and use a salted version of that PIN plus other secret
-     * to encrypt traffic.
-     * - All communication to/from the remote device MUST be encrypted and signed
-     * to prevent image injection and other man-in-the-middle type attacks.
-     * - generateChallenge() and revokeChallenge() MUST be implemented on both
-     * remote and local host (e.g. hash the result of the remote host with a
-     * local secret before responding to the API call) and any transmission of
-     * the challenge between hosts MUST be signed to prevent man-in-the-middle
-     * attacks.
-     * - In the event of a lost connection, the result of the last
-     * generateChallenge() MUST be invalidated and the process started over.
-     * - Both the remote and local host MUST honor the timeout and invalidate the
-     * challenge.
-     *
-     * This method triggers the IBiometricsFaceClientCallback#onEnrollResult()
-     * method.
-     *
-     * @param hat A valid Hardware Authentication Token, generated as a result
-     *     of a generateChallenge() challenge being wrapped by the gatekeeper
-     *     after a successful strong authentication request.
-     * @param timeoutSec A timeout in seconds, after which this enroll
-     *     attempt is cancelled. Note that the framework can continue
-     *     enrollment by calling this again with a valid HAT. This timeout is
-     *     expected to be used to limit power usage if the device becomes idle
-     *     during enrollment. The implementation is expected to send
-     *     ERROR_TIMEOUT if this happens.
-     * @param disabledFeatures A list of features to be disabled during
-     *     enrollment. Note that all features are enabled by default.
-     * @return status The status of this method call.
-     */
