Is there a way to get the a video file or thumbnail for a video through the linkedin v2 api?

Question

We're able to get metadata about videos via the ugcPosts endpoint and analytics via videoAnalytics, but I'm trying to get the actual video file or a thumbnail of the video.

I'm trying hitting: https://api.linkedin.com/v2/assets/<ID>?fields=id,recipes&oauth2_access_token=XXX&projection=(*,recipes*(*), privatePlayableStreams*(*),playableStreams*(*))

But the response doesn't have any urls in it:

{
    "recipes": [
        {
           "recipe": "urn:li:digitalmediaRecipe:feedshare-video-captions-thumbnails",
            "status": "AVAILABLE"
        }
    ],
    "id": "XXX"
}

I'm not sure if the data is not available or if I've got the projection wrong or something else.
