    with:
      azure-dir: ""  # skip Azure check

  check-code:
    uses: Lightning-AI/utilities/.github/workflows/check-code.yml@main
    with:
      actions-ref: main  # normally you shall use the same version as the workflow

See usage of other workflows in .github/workflows/ci-use-checks.yaml.
