Share function should offer sharing via social networks (e.g., facebook, twitter, Google Classroom)

Which file contains the sharing the code script? Maybe that feature can be made more interactive using some social network icons and other similar things.

The issue does not identify a file, test, or entry point. First locate the existing share function and determine how the current sharing flow works; then clarify which networks and interactions are required. Done means the sharing UI supports the agreed networks and its behavior is verified.
