Hello, I don't want site visitors to see what all the quizzes on the site are. I don't want them to see a list of quizzes or a list of categories. I just want them to see the quiz I want them to solve.
All this can be set somehow, I already have it.

But there is still one problem with it. Next to the "Start quiz" button on the left is the "Cancel" button. When the visitor presses CANCEL, the list of quizzes is always displayed.
I don't want him to see the quiz list. How to do it? Can it be done so that when he presses "Cancel" he goes to the home page of the website for example, but not to the quiz list or the category list or the course list?
I don't want any visitor to know what all the quizzes on the site are. Can it be set? And how?

Or is it possible to completely remove the "Cancel" button?
