Reply To: "woocommerce_loop_add_to_cart_link" replacement and "woodmart-add-btn" class

PS: to make it works in quick view mode I needed to add “button product_type_simple add_to_cart_button ajax_add_to_cart add-to-cart-loop” class to the button there
$button = '<a class="" href="' . $product->get_permalink() . '"><span>' . $button_text . '</span></a>';
