When you are on a course page without being enrolled, you can only view the general information and the table of contents: a notice at the top of the page will propose you to log in to POK and, if you have already done so, to enrol in the course to see its full content.
Go to “self enrol into this course”.
Register for the course” and then to “Enrol me”. You will then be able to access the courses you have enrolled in directly from your dashboard.
