Good morning, @rbekhunadze ...
Canvas Community members are not able to check if you have Studio properly set up in your school's Canvas environment. As fellow Canvas users like yourself, we are only able to access our own Canvas environments. Community members are not able to access the Canvas environments of other schools. If you have the "Studio" icon on your left-hand side global navigation bar, you should be able to enable quizzes as part of Studio videos in your library. As a Canvas admin:
- Click on the "Studio" icon on the far left-hand side global navigation menu.
- Click on the three-lined hamburger icon just to the left of "My Library" at the top left corner of the Studio interface.
- Click on "Settings" within the slide-out menu that appears.
- Within the "Permissions" tab, make sure that "Add video quizzes to media" has been toggled on (green) for the "Teacher" role. I'm guessing that you would not want this enabled for the "Student" role, but I'll leave that for you to decide.
If you follow these instructions, you should be able to add a quiz to videos in your Studio library. Here is the Guide on what I've described above:

I hope this will be of some help to you. Sing out if you have any other questions...thanks!
