How to use the @nestjsx/crud-request/lib/request-query.parser.RequestQueryParser function in @nestjsx/crud-request

intercept(context, next) {
        const req = context.switchToHttp().getRequest();
        const controller = context.getClass();
        const options = reflection_helper_1.R.getCrudOptions(controller);
        const parsed = request_query_parser_1.RequestQueryParser.create()
            .parseParams(req.params, options.params)
            .parseQuery(req.query)
            .getParsed();
        const crudReq = {
            parsed,
            options: {
                query: options.query,
                routes: options.routes,
                params: options.params,
            },
        };
        req[constants_1.PARSED_CRUD_REQUEST_KEY] = crudReq;
        return next.handle();
    }
};
