<?php
$_helper = $this->helper(‘Magento\Catalog\Helper\Output’);
$_product = $block->getProduct();
?>
<div class=”product attribute directions”>
<div class=”value”><?php echo $_product->getData(‘use’); ?> </div>
</div>
same you can use for the directions just remember i am using an custom attribute that i made “use” and added to the attribute set.
With this you can add custom tabs in Magneto 2 for the product page without any problem
