From my back end im getting an object which is shown in the screenshot below

In the angular side how can i convert it to image which is a qrcode,because i don't see any bytes there to convert it,is this object valid to be shown as a qrcode?

on my back end i send data from .netcore which is :

  public async  Task<IActionResult> ExecuteAsync(TreydModel treydmodel, CancellationToken cancellationToken)
    {
        string txtQRCode = "morteza";
       var sendPayinResponse=await  sendpaying.SendPayinInitiateRequest(treydmodel);
        QRCodeGenerator _qrCode = new QRCodeGenerator();
        QRCodeData _qrCodeData = _qrCode.CreateQrCode(txtQRCode, QRCodeGenerator.ECCLevel.Q);
        QRCode qrCode = new QRCode(_qrCodeData);
        Bitmap qrCodeImage = qrCode.GetGraphic(20);
        BitmapToBytesCode(qrCodeImage);
        return new OkObjectResult(qrCodeImage);

    }
    private static Byte[] BitmapToBytesCode(Bitmap image)
    {
        using (MemoryStream stream = new MemoryStream())
        {
            image.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
            return stream.ToArray();
        }
    }
