    overlayHandle = CreateOverlay("WatchOverlayKey", "WatchOverlay");

    var filePath = Application.streamingAssetsPath + "/sns-icon.jpg";
    SetOverlayFromFile(overlayHandle, filePath);

    SetOverlaySize(overlayHandle, 0.5f);

-   var position = new Vector3(0, 2, 3);
-   var rotation = Quaternion.Euler(0, 0, 45);
-   SetOverlayTransformAbsolute(overlayHandle, position, rotation);

    ShowOverlay(overlayHandle);
