 Add that to the PR.
 
+A command to do this is `make new-changelog`

 If a PR does not warrant a changelog, the CI check for a changelog can be skipped by applying a `changelog-not-required` label on the PR. If you are making a PR on a release branch, you should still make a new file in the `changelogs/unreleased` folder on the release branch for your change.
