When calling the GET /activities/{id} endpoint, I referred to the sample JSON structure in the Strava API documentation. I noticed this section:

"highlighted_kudosers" : [ {
    "destination_url" : "strava://athletes/12345678987654321",
    "display_name" : "Marianne V.",
    "avatar_url" : "https://dgalywyr863hv.cloudfront.net/pictures/athletes/12345678987654321/12345678987654321/3/medium.jpg",
    "show_name" : true
  } ]

However, when I made the actual request, I didn't receive any highlighted_kudosers field in the response. What could be the reason for this? I want to display the avatars of these highlighted kudos users. How can I achieve this? Do I need to call additional endpoints to get this information? My question is, since the highlighted_kudosers field exists in the official documentation's sample JSON, why is it completely absent in the actual response? Here is the JSON returned by my actual request:
