I am trying to customize the Slug for jobs. I am following the tutorial here: https://wpjobmanager.com/document/tutorial-changing-the-job-slugpermalink/
I am not really understanding the domain parameter you have provided in the very first example “Changing the permalink base using filters”, you give:
$args['rewrite']['slug'] = _x( 'careers', 'Job permalink - resave permalinks after changing this', 'job_manager' );
What is the significance of the ‘job_manager’ domain value??
