I want to group AddShape() figures in EPPlus C#

I am writing to ask you a question because I did not know how to use the Group method when I looked at the EPPlus website.
You can place the figures on the sheet by simply adding them to ws(WorkSheet) as follows, but I would like to group them together.

ExcelShape shape=ws.Drawings.AddShape($"AAA", eShapeStyle.Rect);

The EPPlus WorkSheet object has a method called Group(), but I don't know how to use it.
Can someone teach me?
