How do I integrate bread crumbs into the theme?

Hi there,

this article provides how with the Yoast plugin ( although the same process will apply with other SEO plugins ):

https://docs.generatepress.com/article/adding-breadcrumbs/

add_action ('generate_after_header', 'bread-crumb');
function example_function_name () {?>
<?php
if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb( '<p id="breadcrumbs">','</p>' );
}
?>
<? php}

I wrote the code like above. It did not work

Follow this guide here:
