User story: As a teacher I want to restrict access to activities. I want the activity to be greyed out, so that students can see that it is (or will be) there, but not expose all criteria for visiblity, because some of them are private/secret.

I would like to configure each restriction

• whether not meeting the restriction should hide the activity entirely (this already exists in form of the eye-icon)
• whether the criteria (not the activity!) should be visible, if not met (with a fa-user-secret icon)

Case 1: I have a time constrained activity with addictional secret criteria (linked by OR statements). This activity should be greyed out so that students can see that it will appear sometime soon. There is an additional activity (e.g. a URL to a Zoom-meeting) to be clicked beforehand based on the group of a student. Students have to complete "their" meeting without knowing that other meetings exist. In the current state setting up an "OR" linked restriction (complete Meeting OR Meeting OR Meeting etc.) gives confusing hints what to do next. Disabling the visibility of the restriction (Meeting OR Meeting OR ...) hides the activity alltogether and provokes unnecassary calls from 1000 students.

Case 2: I have an activity that requires the completion of a task, but students with disabilities (belonging to a group - as it is a large course) can bypass the completion of the task. The other students should not be confused by seeing the restriction to be in a group with disabilities nor should the activity be hidden altogether just do hide some restriction criteria.
