Android Native share (intent) an image with a link

Hi, I'm trying to share via the android native sharing service a screenshot + a link to my application. The screenshot part is working perfectly though i don't see the text (tried to share with Facebook, twitter and whatsapp).

Here is my code (mostly taken from here):

 public IEnumerator ShareScreenshot(string extraSubject, string extraText)
 {
     isProcessing = true;
     // wait for graphics to render
     yield return new WaitForEndOfFrame();
     
     // create the texture
     var width = Screen.width;
     var height = Screen.height;
     var tex = new Texture2D(width, height, TextureFormat.RGB24, false);
     // Read screen contents into the texture
     tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
     tex.Apply();
    
     byte[] dataToSave = tex.EncodeToPNG();
     string destination = Path.Combine(Application.persistentDataPath, System.DateTime.Now.ToString("yyyy-MM-dd-HHmmss") + ".png");
     File.WriteAllBytes(destination, dataToSave);
     if (!Application.isEditor)
     {
         // block to open the file and share it ------------START
         AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
         AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
         intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
         AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
         AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "file://" + destination);
         intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);

         intentObject.Call<AndroidJavaObject>("setType", "text/plain");

         //add data to be passed to the other activity i.e., the data to be sent
         intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), extraSubject);
         intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), extraText);

         intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");
         AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

         AndroidJavaObject jChooser = intentClass.CallStatic<AndroidJavaObject>("createChooser", intentObject, "Share Via");
         AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
         currentActivity.Call("startActivity", jChooser);
     }

     isProcessing = false;
     buttonShare.enabled = true;
     ButtonRestart.enabled = true;
 }
