# The @acme/eng-team will be requested as a reviewer.
@acme/eng-team:team
```

### `required`

This user or team is always notified (through a comment) and is a required approver on the pull request regardless of the approvals coverage of other owners. Since the owner specified with `:required` is always required regardless of the owners hierarchy, this should be rarely used because it can make some changes such as global refactorings challenging. `:required` should be usually reserved for highly sensitive changes, such as security, privacy, billing, or critical systems.

> **💡 Note:** Most of the time you don't need to specify required approvers. Non-modified
> approvers are usually enough so that correct reviews are enforced.
