How to connect two ovals with an arrow using OpenXml SDK?

Question

I am trying to use this code for creating two ovals and line. My code is based on the xml in which I connected two ovals. So at the end I woukd like to have two ovals that are connected with an arrow, and remain connected after moving one of the oval.

    public async Task WriteAsync()
    {
        var text = "Example text in the text box";
        Paragraph para = new Paragraph();
        Run run = new Run();
        run.AppendChild(new Text("There are two oval:"));
        para.AppendChild(run);
        body.AppendChild(para);

        var ovalHeight = 61;
        var ovalWidth = 112;

        var oval1leftMargin = 0;
        var oval1topMargin = 50;
        Oval oval1 = new Oval()
        {
            Id = "oval1",
            Style = $"position:absolute;width:{ovalWidth}pt;height:{ovalHeight}pt;margin-left:{oval1leftMargin}pt;margin-top:{oval1topMargin}pt;visibility:visible",
            FillColor = "white",
            StrokeColor = "black",
        };
        
        TextBox ovalTextBox = new TextBox();
        TextBoxContent textBoxContent = new TextBoxContent();
        Paragraph paragraphInOval = new Paragraph();
        Run runInOval = new Run();
        Text textInOval = new Text(text);
        runInOval.AppendChild(textInOval);
        paragraphInOval.AppendChild(runInOval);
        textBoxContent.AppendChild(paragraphInOval);
        ovalTextBox.AppendChild(textBoxContent);
        oval1.AppendChild(ovalTextBox);

        var oval2leftMargin = 240;
        var oval2topMargin = 20;
        Oval oval2 = new Oval()
        {
            Id = "oval2",
            Style = $"position:absolute;width:{ovalWidth}pt;height:{ovalHeight}pt;margin-left:{oval2leftMargin}pt;margin-top:{oval2topMargin}pt;visibility:visible",
            FillColor = "white",
            StrokeColor = "black",
        };
        
        V.Shapetype connectorType = new()
        {
            Id="connectortype1",
            Oned=true,
            Filled=false,
            CoordinateSize= "21600,21600",
            EdgePath= "m,l21600,21600e"
        };
        connectorType.Append(new V.Path()
        {
            ShowArrowhead=true,
            AllowFill=false,
            ConnectionPointType=ConnectValues.None,
        });
        connectorType.Append(new O.Lock()
        {
            Extension = ExtensionHandlingBehaviorValues.Edit,
            ShapeType=true
        });
        V.Shape connector = new V.Shape() {
            Id="connector1",
            Type= "connectortype1",
            ConnectorType=ConnectorValues.Straight,
        
        };
        connector.Append(new V.Stroke()
        {
            EndArrow=StrokeArrowValues.Block,
        });

        
        Picture picture = new Picture();
        Group group = new Group()
        {
            Id = "group1",
            HorizontalPercentage = 100,
            Style = "width:451.3pt;height:270.8pt;mso-position-horizontal-relative:char;mso-position-vertical-relative:line",
            EditAs = EditAsValues.Canvas,
            CoordinateSize= "7200,4320",
            CoordinateOrigin= "2357,4014"
        };
        group.Append(new O.Lock()
        {
            AspectRatio=true,
            Extension = ExtensionHandlingBehaviorValues.Edit,
        });

        group.AppendChild(oval1);
        group.AppendChild(oval2);
        group.Append(connectorType);
        group.Append(connector);
        picture.AppendChild(group);
        Paragraph paragraphWithPict = new Paragraph();
        Run runwithPicture = new Run();
        runwithPicture.AppendChild(picture);

        paragraphWithPict.AppendChild(runwithPicture);
        body.AppendChild(paragraphWithPict);
        mainDocumentPart.Document.Save();
    }
