I'm trying out the new bucket components and with it being S3 compatible i assumed i could configure CORS for signed URLs via that interface. However when i try to do so i get the following error:

"failed to ensure S3 CORS configuration: failed to configure S3 CORS (check s3:PutBucketCORS permission): operation error S3: PutBucketCors, https response error StatusCode: 403"

Since this is a feature flagged component i'm wondering if this is because this config isn't supported yet, or because of some mistake on my end when trying to configure it?

Docs on the bucket are quite sparse so i'm asking here
