> Hi friends I have installed size mapping plugin and I added it to Kibana meta fields too I could successfully enable "\_size" in Elasticsearch via bellow command and see the result in kibana PUT logstash-2023-06-06 { "mappings": { "\_size": { "enabled": true } } } but I could just enable size field in a single upcoming index, how to enable \_size mapping in all of my upcoming indices and index template? should I add it in Kibana index template or elasticsearch?
