How to display text block on specific product pages in Woocommerce?

Question

WordPress

Hello! Tell the experts how to display a text block through a hook on certain product pages. I am writing such a function for the function.php file

add_action( 'woocommerce_before_add_to_cart_form', 'my_infa' );
function my_infa() {
if (is_product('stedt-dh-150')) {
echo '<div class="contex-cats">Акция!!! подарок</div>';
}
}

Using this code, it displays "Promotion!!! gift" on all pages with the product, although it is only necessary on the page with the stedt-dh-150 slug and a couple more pages (how to list them in the code?). Tell me how to write correctly so that it works.

function my_infa() {
    if ( is_product() && get_the_ID() == 10 ) {

    }
}
