Spring boot: Exposing elastic search indices data using elastic search port. For instance, http://localhost:9200/_cat/indices should show my indices

I have a spring boot application where I could see my indices files in "nodes" folder but when I connect it to http://localhost:9200/_cat/indices I could not see any indices. Probably I am not using elasticsearch-rest-high-level-client. I am looking for an experienced developer who could configure elasticsearch client in my spring boot application and expose those data on elasticsearch port. I want to see my indices data on http://localhost:9200/_cat/indices
