AWS CloudWatch now offers native support for the OpenTelemetry Protocol (OTLP) when using AWS Signature Version 4 (SigV4) authentication, as detailed in the AWS documentation. Given this, I want to confirm if Fluent Bit can be configured to send OpenTelemetry (OTEL) logs to CloudWatch OTLP endpoints using SigV4 authentication.
