What is the lowest tier OpenSearch will work with in Amazon S3?

Hello, I’d like to confirm if Opensearch’s repository-s3 plugin works with Glacier Instant Removal.

We have found this documentation

Which mentions that the S3 bucket shouldn’t have glacier tiered objects. Is this not updated and it means “old” glacier as in currently Glacier Flexible Retrieval or does it mean any Glacier Tier?

Update:

A snap and meta files were moved to the Glacier Instant Retrieval tier and successfully restored with the snapshot API.
