Cannot figure out elasticsearch and owncloud.

I need some help figuring out elastic search. My end goal at the moment is to get the full text search owncloud app working. They are both in docker containers (docker compose). I am able to input my url in the owncloud settings (http://es01:9200) and hit setup index. After that it does not index anything or I think pass on anything to elasticsearch at all. Which leads me to my second thing. Cant figure out how to use kibana to help debug anything. I have no idea if owncloud is trying to send any data to elastic. It currently just says "0 nodes marked as indexed, 0 documents in index using 225 bytes".

Here is my compose file. Kind of a hodge podge mix of things from the web to get it to even start 😅.
docker-compose.yml
.env
