How to configure Functions settings/annotations in project.yml

One can secure their Functions via UI Settings -tab: the option Secure Web Function can be enabled. However, when re-deploying the function via doctl, the Secure Web Function (or any other) setting doesn’t persist.

The relating properties are available in the function metadata annotations which can be obtained via cmd doctl serverless functions get demo/test_auth for an already existing function:

{
  "annotations": [
    {
      "key": "web-export",
      "value": true
    },
    ...,
    {
      "key": "raw-http",
      "value": false
    },
    {
      "key": "provide-api-key",
      "value": false
    },
    {
      "key": "require-whisk-auth",
      "value": false
    },
    {
      "key": "exec",
      "value": "python:3.9"
    }
  ],
   ...

How to configure the “Raw HTTP”, “Secure Web Function”, etc., settings in the project.yml, what are the correct field names? I’ve tried the snippet below as my project.yml, with no luck:

packages:
  - name: demo
    actions:
      - name: test_auth
        annotations:
          require-whisk-auth: true
          raw-http: true
        runtime: 'python:default'
        limits:
          timeout: 12000
          memory: 128

Thanks in advance!
