WHY IT NEEDS A POLICY

Why batch-apply-update-action needs a policy

The name suggests applying update actions in batch to ElastiCache/MemoryDB resources (e.g., applying patches or maintenance updates to multiple nodes/clusters). This is an operational action that triggers external operations on AWS infrastructure. Without a description, confidence is reduced, but 'apply update action' implies triggering updates/patches on live systems, which falls under Execute.
