I have currently integrated the enhanced table plugin on my Kibana version 8.16.1 with the hopes that its source code could be modified to integrate an expand action button that will give detailed information on logs. The drill down option is limited to a few options and it mentions having premium access which is why that option is closed down. Any suggestions would be welcome.
The "Drilldown to URL" feature is premium license only, but the "Drilldown to Dashboard" feature is available with a basic license. I would suggest looking at the Developer Examples in Kibana, specifically the UI Actions Enhanced example for details on how a plugin can register actions such as drill downs. You can see the Developer examples by running Kibana from the source code with yarn start --run-examples.
