Develop in Swift Fundamentals iBook

How do you annotate on the iBook "Develop in Swift Fundamentals Xcode 15"? I downloaded it from this link Get the student guide, but when I open it in iBook, I don't have an option to use my iPen to annotate or even highlight specific selections of text. Is this option not available? Can the book be downloaded as a pdf and opened in an app where I can annotate?
