You can pass the context via Temporal headers (not to be confused with HTTP headers).  
Headers are mapping of name to `Payload` that’s embedded in the Temporal API request bodies and history events.  
You can access those headers via interceptors.  
Check the documentation and the opentelemetry module for reference.
