Is there a way to connect janusgraph to an existing opensearch instance as the index backend?

I have an opensearch instance running already which I want to also use as the index backend for janusgraph.

      janusgraph.index.search.backend: elasticsearch
      janusgraph.index.search.hostname: <my-opensearch-hostname>:9200

      janusgraph.index.search.backend: elasticsearch
      janusgraph.index.search.hostname: <my-opensearch-hostname>:9200

      janusgraph.index.search.backend: elasticsearch
      janusgraph.index.search.hostname: <my-opensearch-hostname>:9200

      janusgraph.index.search.backend: elasticsearch
      janusgraph.index.search.hostname: <my-opensearch-hostname>:9200

But this doesn't work and I get the error:

java.lang.IllegalArgumentException: Unsupported Elasticsearch server major version: 2.14.0

java.lang.IllegalArgumentException: Unsupported Elasticsearch server major version: 2.14.0

java.lang.IllegalArgumentException: Unsupported Elasticsearch server major version: 2.14.0

java.lang.IllegalArgumentException: Unsupported Elasticsearch server major version: 2.14.0

Any help would be appreciated. Thank you!
