S3 TransferManager incompatible with AWS X-Ray

Hello

We are currently using XRay for the services we own, and one of the API involves files transfer, so I add the dependency of using S3 `transferManager`. However this throws `XRay "SegmentNotFoundException"`.

Spend a little time checking what is the root cause and it turns out that it is because `transferManager` creates a thread pool and XRay is not able to gather context for the threads that transferManager created.

I am wondering any available solution for this already, having checked the following resources, but no luck
