Capturing Service Layer

Elastic Stack Kibana

I am using co.elastic.otel in my Spring boot project. Everything is working well, except I just see tracing in controller and repository level. I need to trace in service layer as well. How it is possible? My Maven dependency is:

<dependency>
            <groupId>co.elastic.otel</groupId>
            <artifactId>elastic-otel-runtime-attach</artifactId>
            <version>1.4.1</version>
        </dependency>
