Show custom tab in every subcategory product

Hi! I need to display a custom tab in every product listed in the subcategories of the main category called ‘Software Spia’ (https://www.staging2.italsectech.com/categoria/software-spia/)

I’m using this code but it doesn’t work

add_filter( 'woocommerce_product_tabs', 'woo_custom_product_tab' );
function woo_custom_product_tab ( $tabs ) {
	
	// Adds the new tab

  if ( is_product() && has_term( 'Software Spia', 'product_cat' )) 
    { 
      $tabs['avvertenze'] = array(
        'title' 	=> __( 'Avvertenze', 'woocommerce' ),
        'priority' 	=> 55,
        'callback' 	=> 'woo_software_tab_content'
      );
    }

	return $tabs;
}

function woo_software_tab_content() {
	echo '<h4>Ciao</h4>';
}

Any idea on how to solve?
