/**
 * The object that changes the device information.
 *
 * The device information change can be used to
 *  - modify the name of the device and/or
 *  - modify its Firebase registration token or
 *  - disable push notifications.
 *
 * If neither {@link name} or {@link fcmRegistrationToken} are provided, the provided {@link onSuccess}
 * callback will be executed when {@link execute} is invoked.
 *
 * Usage example for changing device information:
 * ```ts
 *   [...]
 *   async updateDeviceInformation(
 *       client: MobileAuthenticationClient,
 *       newName: string,
 *       fcmToken: string
 *   ): Promise<void> {
 *       await client.operations.deviceInformationChange
 *           .name(newName)
 *           .fcmRegistrationToken(fcmToken)
 *           .onSuccess(() => {
 *               // handle success
 *           })
 *           .onError((_error) => {
 *               // handle error
 *           })
