Hello. I'm trying to add a Lifecycle Rule to a S3 bucket that includes a minimum file size directive. I've review this doc, but don't see what the param name would be. Is minimum object even supported?

Looks like this is on the V2 interfaces https://www.pulumi.com/registry/packages/aws/api-docs/s3/bucketlifecycleconfigurationv2/#objectsizegreaterthan_csharp

Is there a way in v1? I can't use v2 as our entire S3 bucket mgmt project is v1.

I think you can use the V2 configuration types with a V1 bucket. BucketLifecycleConfigurationV2 just takes the bucket name, I don't think it matters how that bucket was created.
