A pop-up will appear, allowing you to enter text freely. After entering your comment, press the 'Add' button to add the comment to the selected location.
All comments added to a document are displayed in the sidebar that appears when you click the 'Edit Comments' icon on the toolbar, and clicking a comment will take you to the added section.
