Hi. Is it possible to add custom headers to the data the RUM agent sends from the frontend application - for things like the name of a frontend test making a browser request, or the release version of the frontend application in which RUM is instrumented?
I would like to get that data as part of the span data to better track context of the spans created in Elastic. Wondering if this could provide trace-based testing without the need for a dedicated tool for that purpose.
Thanks!
