How to collect thread.id as an attribute to logs?

[victorChou1024]

I follow the docs at https://signoz.io/docs/userguide/collecting_application_logs_otel_sdk_java/#settings-for-appender-instrumentation-based-on-the-logging-library.
And my startup shell is as follow:
java -javaagent:./${AGENT_FILE} -jar helloworld-0.0.1-SNAPSHOT.jar -Dotel.instrumentation.logback-appender.experimental-log-attributes=true

but i can not get the thread.id field at frontend.

My source codes import no otel libs. Did i miss some configs or something?
