Get Portfolio Category and Display it on page

I can show post categories on normal post pages by making this shortcode:

function myshortcode_category( ){
return get_the_category( $id )[0]->name;
}
add_shortcode( ‘page_category’, ‘myshortcode_category’ );

But the same shortcode doesn’t work with portfolio categories. Can you tell me how to modify this to display portfolio category instead?
