Posts request for a public pages

Question

Dear developers, Recently, I have been using the latest version of LinkedIn's API, specifically the "POST" feature. When I request data about posts from non-public page organizations, the API successfully retrieves all posts. However, when I switch to public pages, the API does not retrieve any data. What could be the reason for this? Do I need additional privileges? This is the request: .../posts?q=author&author=urn%3Ali%3Aorganization%3A75345323&count=1 Response:

{
    "paging": {
        "start": 0,
        "count": 1,
        "links": [],
        "total": 0
    },
    "elements": []
}

Thanks, Greetings.
