Hi,
Look for the post request. You will see some variable as action:”post_update” or something similar. Then look into your themes ajax.php(most probably in _inc/ajax.php) for a hook wp_ajax_{the action_name} , i.e. wp_ajax_post_update in this case. There will be a function attached to that. You can put your debug code in that function.

rest is correct on your setup. The request will always go to wp-load.php, so that is right. Just investigate the attached function for debugging.
