How to add a line below category meta and social share button

How can I add a LINE and SOCIAL SHARE buttons below the category meta in single product page.

I have successfully added a line below the “add to cart” button using the code:
add_action( ‘woocommerce_after_add_to_cart_button’, ‘add_content_after_addtocart_button_func’ );

function add_content_after_addtocart_button_func() {

// Echo content.

echo ‘<div class=”second_content”>Place your content here!</div>’;

}

But I don’t know how to do it below the category meta.

Here’s my single product page link:
