What role enables someone to authorize a request, with no other permissions on the platform?

`Approval Group` is not a standard role for individual users to authorize requests; it refers to a group of users who might collectively approve.

`Authorize [authorize_user]` is not a standard or recognized role in ServiceNow for simply authorizing requests.

`Reviewer [reviewer_user]` is not a standard role primarily intended for authorizing requests; it implies reviewing content or tasks.

`Verification [verify_user]` is not a standard role primarily intended for authorizing requests; it implies verifying information or processes.

The `approver_user` role is specifically designed in ServiceNow to allow users to approve or reject records, providing only the necessary permissions for authorization without granting broader platform access.
