Not able to integrate async-profiler with the APM agent

Elastic Observability

Hello,

Need to capture native threads and method information with profiling information.

 profiling_inferred_spans_enabled=true
 profiling_inferred_spans_sampling_interval=50ms
 profiling_inferred_spans_min_duration=250ms
 profiling_inferred_spans_logging_enabled=true
 profiling_inferred_spans_lib_directory=/opt/async-profiler-2.9-linux-x64/build/libasyncProfiler.so

Added above configuration in elasticapm.properties file. Not able to capture any information of native threads or CPU profiling information under APM in kibana. Pls let me know how can it be captured.
