We are running a Kotlin service that regularly uploads large files to S3.
Currently we have our own multipart upload logic that uses the S3AsyncClient, but we want to use S3TransferManager as it already contains multipart logic.
We have configured the S3AsyncClient to use a custom AwsMetricsPublisher to publish metrics to Micrometer. These metrics include the number of uploaded files, chunks, their sizes and others.
How can we configure S3TransferManager to publish these metrics? I can't find anything in the documentation or in existing code.
