How to return x-be-traceid to the caller?
In my cluster, istio is generating x-b3-traceid and is propagating to the application. And application is using open telemetry tracing with b3multi type and I am successfully able to collect the traces in Tempo.
But I am thinking it will be great if we give user the x-b3-traceid so that he can directly take the traceid and search in tempo.

Any option to do it (by using envoy proxy or vitual service, etc)?
