Create this cross-account IAM role?

Situation

The data team needs to share anonymized analytics with a partner. Kimi generated a script to create a cross-account IAM role for S3 access.

Environment

The partner account ID is 123456789012. The shared S3 bucket is company-data-bucket. An external ID is configured in the partner's integration. The role should only allow S3 GetObject on the shared prefix.
