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);

const range = shape.GetTextRange();
const range1 = range.GetRange(0, 7);
