Unable to export traces to elastic search engine backend

I am not able to export generated traces from opentlemetry collector to elastic search backend, when i checked logs of collector pod it results with below error:

This appears to be a problem with the backend? Maybe someone from elastic can help here. Pinging @andrzej-stencel

It looks like you are trying to send traces to Elasticsearch using the OTLP exporter, but Elasticsearch does not accept OTLP directly, unless you add the APM Server in front of it.

Instead, you should use the Elasticsearch exporter to export traces to Elasticsearch.

Hello @andrzej-stencel , when tried with elasticsearch/trace exporter pod going to crash loopbackoff saying with below error

• error decoding 'exporters': unknown type: "elasticsearch" for id: "elasticsearch/trace" (valid values: [otlphttp debug logging nop otlp])
  2024/05/31 10:30:47 collector server run finished with error: failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:
