I have successfully coded textboxes, arrows (lines), and sticky notes but I cant figure out hoe to add a high light. I followed the same patter with the other three but highlights elude me. What goes in the type casting parenthesis ? Please advise.

Here is a snip of my code:

var docPages = (LFDocumentPages)_document.Pages;
var firstPage = (LFPage)docPages.Item[1];

var highlight = (WHAT GOES HERE?) firstPage.AddAnnotation(Annotation_Type.ANN_HIGHLIGHT);

Highlights, redactions, strikeouts and underlines are all of type LFLinkedAnnotation, here is an example:

LFLinkedAnnotation highlightAnn = (LFLinkedAnnotation)page.AddAnnotation(Annotation_Type.ANN_HIGHLIGHT);
LFRectangle highlightRect = highlightAnn.AddRectangle();
highlightRect.Left = 100;
highlightRect.Top = 100;
highlightRect.Right = 200;
highlightRect.Bottom = 200;
highlightAnn.Color = 0xFF0000;
page.Update();
