Meta: "Resource not accessible by integration" in github workflow

The workflow to auto-request a changelog in incoming PRs isn't working, it seems to always generate an error and it doesn't add the desired comment to the PR. Example from one of mine:

https://github.com/beetbox/beets/actions/runs/7074741000/job/19256121899

Start with the linked GitHub Actions run and identify the workflow that auto-requests a changelog on incoming pull requests. Trace the reported "Resource not accessible by integration" error and verify the workflow can complete and add the expected changelog comment to a pull request.
