Not working when added through functions.php

Hi,

So I need to display a widget through a shortcode on Wooocommerce’s single product page by adding it through functions.php. Here’s what I’ve tried but it’s not working:

add_filter( 'woocommerce_short_description', 'custom_woocommerce_short_description' );

function custom_woocommerce_short_description( $description ) {
global $post;

$description = $description . do_shortcode('[widget id="mks_author_widget-3"]') ;

return $description;
}

What could be the issue?

Thanks
