let stroke = Api.CreateStroke(0, Api.CreateNoFill());
let shape = worksheet.AddShape("flowChartOnlineStorage", 120 * 36000, 70 * 36000, fill, stroke, 0, 2 * 36000, 0, 3 * 36000);
let content = shape.GetContent();
let paragraph = content.GetElement(0);
paragraph.RemoveAllElements();
let run = Api.CreateRun();
run.AddText("This is the first paragraph element. ");
paragraph.AddElement(run);
run = Api.CreateRun();
run.AddText("This is the second paragraph element. ");
paragraph.AddElement(run);
run = Api.CreateRun();
run.AddText("This is the third paragraph element (it will be removed from the paragraph and we will not see it). ");
paragraph.AddElement(run);
paragraph.AddLineBreak();
run = Api.CreateRun();
run.AddText("This is the fourth paragraph element - it became the third, because we removed the previous run from the paragraph. ");
paragraph.AddElement(run);
paragraph.AddLineBreak();
run = Api.CreateRun();
run.AddText("Please note that line breaks are not counted into paragraph elements!");
paragraph.AddElement(run);
