AWS Lambda Java traces not joined

[Sutty100]

Describe the bug
When Lambda A calls Lambda B via API Gateway the trace is not joined up in either Elastic APM, Zipkin however it is in X-RAY.

Steps to reproduce
Create two Lambdas that are both invoked via API Gateway. Have the first lambda call the second via API Gateway. Have an OpenTelemetry collector exporting to X-RAY, Elastic, Zipkin.

What did you expect to see?
A single trace showing Lambda A calling Lambda B in Zipkin and Elastic not just XRAY.

What did you see instead?
Two separate traces with Lambda A showing an outgoing http request

What version of collector/language SDK version did you use?
Lambda Layer: aws-otel-java-agent-amd64-ver-1-32-0:3
Java Version: 21
OpenTelemetry Collector: opentelemetry-collector-contrib:0.116.1
