Is it possible to share one's schedule publicly by sharing calendar app URL?
~/community/apps/canvas/calendar/super-user
~/community/apps/canvas/calendar/user-a
The last URL path doesn't seem to be respected.
No matter what the user ID is, you are bound to access your own calendar app only.
Also, you are required to login to access the calendar app. (It could be obvious with respect to current logic since the user is only able to access one's own calendar.)
