Removing heading "Additional information"

Hi,
I removed the heading “product description” INSIDE the tag on the product page by inserting this code into my child theme’s functions.php:

add_filter( 'woocommerce_product_description_heading', 'remove_product_description_heading' );
function remove_product_description_heading() {
return '';
}

I tried to do the same for the heading “additional information” but it didn’t work…could someone please help me out?

Thank you very much.
