Use assume role - AWS_ROLE_ARN - instead of access/secret key

[Hankier]

Problem

Is it possible to use s3 in cubestore on eks with assume role instead of access/secret?
I see that implementation of remoteS3 is checking for CUBESTORE_ prefixed values. There is nothing like CUBESTORE_AWS_ROLE_ARN or sth that would allow to use role instead of keys.

Tried to run those helm-chart on EKS with AWS_ROLE_ARN from rust-s3 but it failed.

Is this possible to use ARN and I did sth wrong. Or yet its not implemented in cubestore?
