+namespace App\Nova\Exports;
+
+use Coreproc\NovaDataSync\Export\Nova\Action\ExportNovaAction;
+
+class ProductExportAction extends ExportNovaAction
+{
+    protected function processor(ActionFields $fields, Collection $models): ExportProcessor
+    {
+        return new ProductExportProcessor($fields->get('start_date'), $fields->get('end_date'));
