This issue presents the goals needed for the Activity Feature focusing on the changes in Sidenav and path limitations.

Checklist:

• Only the users with Educator role can see the 'Create Activity Button' on the sidenav.
• Users with 'Creator' roles should not be able to see the activity creation form if they manually visit the endpoint '/activities/create' and see a warning saying that only educators can create activities.
• 'Explore Activities' button in the sidenav should redirect the users to activities list page '/activities'
