Custom SKU Field is added but not showing on Product page (WooCommerce)

Custom SKU Filed Issue in WooCommerce

Dear All,

I am trying to add a Custome field just near by to SKU and Availablity in Single Product Page in WooCommerce by following code added in my Child Theme function.php.

//****Adding a text field:****//

function jk_add_custom_sku() {
$args = array(
'label' => __( 'Custom SKU', 'woocommerce' ),
'placeholder' => __( 'Enter custom SKU here', 'woocommerce' ),
'id' => 'jk_sku',
'desc_tip' => true,
'description' => __( 'This SKU is for internal use only.', 'woocommerce' ),
);
woocommerce_wp_text_input( $args );
}

//**Saving the Custom Meta Field***//
function jk_save_custom_sku( $post_id ) {
// grab the custom SKU from $_POST
$custom_sku = isset( $_POST[ 'jk_sku' ] ) ? sanitize_text_field( $_POST[ 'jk_sku' ] ) : '';

// grab the product
$product = wc_get_product( $post_id );

// save the custom SKU using WooCommerce built-in functions
$product->update_meta_data( 'jk_sku', $custom_sku );
$product->save();
}

add_action( 'woocommerce_process_product_meta', 'jk_save_custom_sku' );

It is added a new Custom SKU Filed in Inventry section successfully. Now I am trying to display it frontend at the product page but it is not showing. Now is the solution for this?
