Is there support for getting instance_type_offerings for OpenSearch instance types?

Presently this doesn’t look like it is returning any instance types using any of the OpenSearch instance types (e.g. m5.large.elasticsearch).

Is there a way to get the list of instance types for OpenSearch available in an AZ like the data “aws_ec2_instance_type_offerings” resources does?

Looks like this is now tracked in New Data Source for Listing Available Instance Types for OpenSearch · Issue #22696 · hashicorp/terraform-provider-aws · GitHub and this forum post can be closed.
