Quiz and Q-A Section

Hello,

On a completely fresh WordPress installation (5.8.3), I installed Dozent via WordPress plugin page a few minutes ago. I use the default WordPress theme Twenty Twenty-One. During the course creation process, there is no link for creating a quiz. In addition, when a lecture is created, there is no “discussion” (Question-Answer) section at the bottom of the content. Can you check this, please? Thanks.
