Reply To: Extra content before and after product

I would like to add for example a shortcode to all products in the position of extra box . (I dont want to use extra box in every product separate)
What should I do. is important please help ..

Now I am writing .

add_action( ‘woocommerce_single_product_summary’, ‘custom_shortcode’, 40 );

function custom_shortcode() {
echo do_shortcode(‘[html_block id="16367"]‘);
}

but is going under the tabs (I have the tabs right side and when i open or close the video goes under the main image. )

I would like exactly in the position of Extra content before the meta info (sku categoreis social) and after product descriptions tab.

thank you !
