const presentation = Api.GetPresentation();
const slide = presentation.GetSlideByIndex(0);
slide.RemoveAllObjects();

const fill = Api.CreateSolidFill(Api.RGB(255, 111, 61));
const stroke = Api.CreateStroke(0, Api.CreateNoFill());
const shape = Api.CreateShape("rect", 300 * 36000, 130 * 36000, fill, stroke);
shape.SetPosition(608400, 1267200);

const docContent = shape.GetDocContent();
const paragraph = docContent.GetElement(0);
paragraph.AddText("Hello World");
slide.AddObject(shape);

const range = shape.GetTextRange();
const startPos = range.GetStartPos();

const fill2 = Api.CreateSolidFill(Api.RGB(200, 230, 255));
const shape2 = Api.CreateShape("rect", 300 * 36000, 80 * 36000, fill2, stroke);
shape2.SetPosition(608400, 6000000);
shape2.GetDocContent().GetElement(0).AddText("GetStartPos: " + startPos);
