Image in woocommerce product page via hook

## NO SITE ACCESS PROVIDED ##

I have this code in functions.php that doesn't seem to work:

function insert_content( $post_excerpt ) {
$content = '<a href="/highest-quality-super-foods/" target="_blank"><img src="' . site_url() . '/wp-content/uploads/2020/09/aco-google-shopping.png" width="100px" style="float:right;" class="aco-product"></a>';
return $content.'<br>'.$post_excerpt; }
add_filter('woocommerce_after_add_to_cart_form', 'insert_content', 10, 1);

If I change the location to

function insert_content( $post_excerpt ) {
$content = '<a href="/highest-quality-super-foods/" target="_blank"><img src="' . site_url() . '/wp-content/uploads/2020/09/aco-google-shopping.png" width="100px" style="float:right;" class="aco-product"></a>';
return $content.'<br>'.$post_excerpt; }
add_filter('woocommerce_short_description', 'insert_content', 10, 1);

Then it shows up in TWO locations (attached screenshot)

Please tell me how to fix my code so it just shows up ONCE after add to cart form

Thanks
