**Kibana version** : 8.5.1

**Elasticsearch version** : 8.5.1

**APM Server version** : 8.5.1 (amd64), libbeat 8.5.1 [7cf6f555935def992ecfd9a4693771447cb51431 built 2022-11-09 11:21:18 -0800 -0800]

**APM Agent language and version** : Elastic.Apm.NetCoreAll 1.23.0

I'm using api gateway (Yarp reverse proxy) in front of all microservices. I have installed `Elastic.Apm.NetCoreAll` in all services + gateway.

This is how apm config looks like in all services and gateway:

```auto
  "ElasticApm": {
    "ServerUrl": "myapmurl",
    "TransactionSampleRate": 1
  }

```

When I check some request in kibana apm in some service, I see all details, sub requests from svc1 to svc2, from svc2 to svc3, db calls etc.  
When I check same request in Api gateway, I see only one http request, no other details.

`TraceParent` and `TraceState` headers are passed from gateway to microservices.  
Is there any additional setup I need to do to make APM work correctly with yarp?
