How to flush for AWS Lambda?

[canadiannomad]

I'm using tracing with opentelemetry-otlp to Jaeger in a lambda... Since lambdas pause and sometimes get killed after use, how can I make sure the spans are sent to the collector? I'd like to use something like force_flush, but I can't seem to find a way to invoke it that works. So I'm likely missing something, as I see no examples, and the force_flush functions are on objects I don't seem to have easy access to.

I can tell the spans get sent when I call the lambda twice after a few seconds..

Any help or suggestions in this direction?
