Rank Math breadcrumbs and GeneratePress

I tried to use this code for the breadcrumbs in GeneratePress -> functions.php:

<?php if (function_exists(‘rank_math_the_breadcrumbs’)) rank_math_the_breadcrumbs(); ?>

This did not work. I did get this error: https://ibb.co/qRk221Z

In stead I used this code I found on the internet:

add_filter( ‘the_content’, function( $content ) {
if( function_exists( ‘rank_math_get_breadcrumbs’ ) ) {
$content = rank_math_get_breadcrumbs() . $content;
}
return $content;
});

This does work.

Questions:

1. Which code is better to use?
2. If code 1 is better. How do I make it work?
