Linkedin JS SDK Share responding with success but

Question

So, I've been messing around with the Share function of the Linkedin's JS SDK.

I've followed their example (under Javascript SDK tab): https://developer.linkedin.com/docs/share-on-linkedin

I've managed to authenticate and make the POST request to their API, and even managed to get a response just like what they show in the docs (with updateKey and updateUrl).

But the Url doesn't work, and when I go to my Linkedin account, the content wasn't shared.

I'm able to make the same POST request several times, always getting a successful response, and nothing is ever shared.

Can anyone help me with this?

Here's the code:

<div id="share-with-linkedin"><i style="color: orange;" class="fa fa-linkedin-square fa-2x" aria-hidden="true"></i></div>

<script type="text/javascript">
// Handle the successful return from the API call
function onSuccess(data) {
  console.log(data);
}

// Handle an error response from the API call
function onError(error) {
  console.log(error);
}

// Use the API call wrapper to share content on LinkedIn
function shareContent() {
  // Build the JSON payload containing the content to be shared
  var payload = { 
    'comment': "OLHA A VAGAAAAA!",
    'content': {
      'title': "My Beautiful Title",
      'description': "My Awesome Description",
      'submitted-url': "https://www.99hunters.com",
      'submitted-image-url': "https://sep.yimg.com/ay/yhst-129804686222317/kiss-concert-poster-1970-5.gif"
    },
    'visibility': {
      'code': "anyone"
    }
  };

  IN.API.Raw("/people/~/shares?format=json")
    .method("POST")
    .body(JSON.stringify(payload))
    .result(onSuccess)
    .error(onError);
}

const linkedinBtn = document.getElementById("share-with-linkedin");
linkedinBtn.addEventListener("click", (event) => {
    shareContent();
});

And a sample successful response:

{
   updateKey: "UPDATE-0-6400457564139581440",
   updateUrl: "https://www.linkedin.com/updates?discuss=&scope=0&stype=M&topic=6400457564139581440&type=U&a=WUeZ"
}
