I'm pretty new to Kibana and to Vega / Vega-lite in particularity, so I apologize if the question is somehow stupid, but I could't find a solution online.
So I'm trying to the Vega visualization interface in my hosted Kibana (Elastic Cloud), but keep getting this error: "External URLs are not enabled. Add vega.enableExternalUrls: true to kibana.yml".
I went through the Kibana documentation and but couldn't understand how do I edit the kibana.yml file.
Any instruction or clarification will be greatly appreciated!
