Hi guys, We are assuming the Bearer Token Refresh task, which was started but now it's been paused for a while (link to original POC) <[link](https://github.com/apache/arrow/pull/8780)>, and we have some concerns about it, such as:
1 During a Flight Call we can get unauthenticated while consuming a stream or just when an operation is started? We were wondering if the creation of a wrapper around the StreamObserver is needed. 2 Would it be better for an Interceptor to make this Authentication? We were basing ourselves on this comment <https://github.com/grpc/grpc-java/issues/5856#issuecomment-511077021>
