I think it would be helpful to add a troubleshooting/debugging guide specifically for AWS Auth and enabling certain OTel libraries (like the ones we have disabled in Lambda)

https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-OTLPTroubleshooting.html

We should also specify the ADOT version that these features are available in. For example if there's a Python customer they have to use version 0.10.0 or higher.
