c# – iOS LocalIdentifier from UIImage

Objective: Utilizing an iOS native technique, push a consumer made image onto their Instagram feed in C#.

public bool ShareImage(byte[] imageByte)
        {
            bool outcome = false;

            //string fileName = "xxx.png";
            //string path = Path.Mix(FileSystem.CacheDirectory, fileName);
            //File.WriteAllBytes(path, imageByte);
            NSData information = NSData.FromArray(imageByte);
            UIImage picture = UIImage.LoadFromData(information);
            
            //NSUrl url = NSUrl.FromString($"instagram://library?AssetPath={path}"); // Solely opens
            NSUrl url = NSUrl.FromString($"instagram://library?LocalIdentifier={1}");
            if (UIApplication.SharedApplication.CanOpenUrl(url))
            {
                UIApplication.SharedApplication.OpenUrl(url);
            }
            return outcome;
        }

So far as I am conscious the way in which I’ve to do that is to avoid wasting my picture to the machine and get a Native Identifier for this.
I’ve constructed this from the snippets of objective-c code I’ve seen. Sharing images solely works with the native app put in, as I’ve learnt from my trials to get the fb module working.
