Steps to reproduce the issue

DO a post request on
{{base_path}}/api/index.php/v1/content/article

We are assume the layout created using the API should be similar to the Joomla Article Manager, We don't have the Article Featured status, not the Article Access level.

Expected result

Should have the value indicating if the article is featured or not and the Access Level Group ID for the Article as well.

Actual result

    "links": {
        "self": "http://localhost/joomla4/api/index.php/v1/content/article"
    },
    "data": [

System information (as much as possible)

Additional comments

It's possible to add feature 1 to the Create/UPDATE api however it's not useful if the the API doesn't tell an article is already featured or not.
