WHY IT NEEDS A POLICY

Why GrantHealthOmicsRepositoryAccess needs a policy

The name suggests this tool grants access (permissions/policies) to a HealthOmics repository, which is a Write/permission-modification action. Granting access can have significant security implications (high severity) as it could expose sensitive health data repositories. Confidence is low due to empty description, but the name is fairly indicative of an IAM/access-control write operation.
