Following code work for me you can try it.

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    $jsonResult['skus'] = [];
        foreach ($subject->getAllowProducts() as $simpleProduct) {
            $jsonResult['skus'][$simpleProduct->getId()] = $simpleProduct->getSku();
    }
    $result = json_encode($jsonResult);

}

}

});

        });
 
        targetModule.prototype._UpdatePrice = updatePriceWrapper;
        return targetModule;
    };
});

Note: this will update SKU on selection you can modify as per your need.
