Correct field for Trace-Id or Request-Id?

While writing an SDK for Haskell, I’m referring to the event-payloads documented at and I couldn’t find any special tag/field for Trace-Id or Request-Id. Also, I noticed which talks about logging NGINX’s $request_id in a regular tag in Sentry.

Therefore, is the following conclusion correct – Sentry has no special treatment for things like Trace-Id or Request-Id and it is left up to the SDK (or the user) to figure out a where/how to store them in the event payload?
