After open AEM Web console click on the sling tab, you will find the "Context-Aware Configuration" option
After Navigate Context-Aware Configuration web console page you will see a form. You can enter the "Content Path" and "Config name" which you want to debug and click on resolve. if you are debugging a collection config check the checkbox "Resouce Collection"
Note: if "cq:conf" property set to your jcr:content node of page sometimes it will read configurations for the path. So keep an eye on "cq:conf" and "sling:configRef" properties.
To know how to develop with Sling context configurations refer to my post Sling Context Aware Configuration AEM 6.5 Examples.
