 ## question 
 Hi there, I am trying to try to use the (Azure Monitor OTEL Exporter)[https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/monitor/azure-monitor-opentelemetry-exporter#microsoft-opentelemetry-exporter-for-azure-monitor] for a python application, and I am having trouble getting data flow when I follow the examples of setting up the exporter. I tried to copy the (hello world sample code)[https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/monitor/azure-monitor-opentelemetry-exporter#export-hello-world-trace] and put my connection string, and I'm still not seeing any tracing data land in my traces table in my App Insights instance. Could I get some help here to figure out what is going on, or where the sample code might not be functional?

 To clarify, changing the type hint is not a breaking change, just annoying to work with a Union return type. The other options of introducing a wrapper class however, would be breaking obviously.
 If this is already acting that way at runtime, it means people already use `isintance` or `try/except AttributeError` anyway, so the `Union` still make things better.
