Link spans trees between microservices

[andreluizsgf]

Hey guys, i have two microsservices, lets say A and B, being traced by opentelemetry. Service A makes HTTP requests to service B and both creates spans but on different trace ids. On the trace from A i can see all http requests made to B but cant see the operations made by B (database operations, another HTTP calls or functions) on the same tree. To achive that i need to access the trace created by B directly. Is there a way to link both of them to the same traceId, since they are the same are born from the same span?

Here is an example of what i want to achieve:

• [ ] This only affects the JavaScript OpenTelemetry library
• [x] This may affect other libraries, but I would like to get opinions here first

Would you mind sharing your setup codes or a minium reproduction of the problem? From my first impression, the problem may related to missing propagators to inject necessary trace contexts into the request sent.
