Where should I add "dockerless: true"

The docs indicate the addition of a custom property:

custom:
  # this section allows for customization of the default
  # serverless-rust plugin settings
  rust:
    # flags passed to cargo
    cargoFlags: '--features enable-awesome'
    # experimental! when set to true, artifacts are built locally outside of docker
+   dockerless: true

And I can see other users adopting this approach: https://github.com/NEU-DSG/dailp-encoding/blob/f0500d5a15201f3f961668aebc3b5a1990d8b649/serverless.yml#L12

However, your test cases place it in a different location: https://github.com/softprops/serverless-rust/blob/f491824d92e11123a9fecf1f58e7c1a24dec77eb/tests/integration/test-func/serverless.yml#L15

Unfortunately wherever I add this option it seems to be ignored ...

$ npm run invoke
