App Update Notification

Hi all,
In our application, we notify the user about app update notification and we re-direct to Win Store of our application page using

  ` //build URI to launch store app
    var uriStore = new Uri(@"ms-windows-store://pdp/?productid=" + storeAppID);
    UnityEngine.Debug.Log("store URL : " + uriStore.ToString());

    LauncherOptions options = new Windows.System.LauncherOptions();
    var fallbackUri = new Uri(AppStoreDetails.GetAppURL());
    options.FallbackUri = fallbackUri;
    // Launch the URI
    var success = await Windows.System.Launcher.LaunchUriAsync(uriStore, options);`

Here we are successfully re-directed to the store page, but we have only Launch button available. When we navigate to any other option and come back to store page, we have option of Launch and Update.

Folks, please provide your inputs, Is there any protocol command that i need to add while constructing URI or any other option available to refresh the store page

Note : Unity 2017, VS 2017

Thanks.
