I read the doc and if I understand it correctly, that is to display Yoast breadcrumbs correct? I don’t use Yoast. Starting to add more sites to GP and never knew if the theme itself has a breadcrumb shortcode? My last theme did but I am moving away from that one!
The doc article is using Yoast as an example but the method to insert shortcode (using hooks) should be the same regardless what plugin you are using for breadcrumbs – you would just use different shortcode in step 2.
