Intercept tracing request (OTLPTraceExporter, WebAutoInstrumenation, Browser)

[krechtern]

Hey,

I'm using the OTLPTraceExporter with @opentelemetry/auto-instrumentations-web in an Angular project (if this matters). Our tracing endpoint requires an Auth-Token and I can't figure out how to intercept the requests made from this library. Is there an official way to add an interception here?

I'm aware that I can provide custom headers when creating the OTLPTraceExporter, but my token will be renewed over time, so I need an interception solution for this.

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