Place add Sharing buttons below Add to cart

Hi, I want to move the sharing buttons to below add to cart button. I’ve tried with customize code here

add_action( 'woocommerce_after_add_to_cart_form', 'htdat_content_after_addtocart_button' );
function htdat_content_after_addtocart_button() {

	// NOTE: replace your category slugs for 'customize-nail'
	if ( is_product() && has_term( array( 'customize-nail'), 'product_cat' ) ) {
		echo '<div class="addthis_inline_share_toolbox"></div>';
}
}

However, I think it is wrong because the buttons didn’t appear. Could you please help me with this. Thank you
