[divyanipunj]

Complete this after issue FEATURE: Adding a Moderator Role to the Backend..

Once the /api/admin/moderators endpoints are fixed, we need a frontend page for Admins to add moderators that uses those endpoints.

Currently (no page under Admin for Moderators) :

Implementation details: This has already been implemented in Frontiers. You can start by checking out: frontend/src/main/pages/Admin/AdminsCreatePage.jsx. You can also explore this codebase to find a structure for the stories, tests, and adding the page to navigation bar.

A/C:

• There is a new page under the admin tab (i.e. ModeratorCreatePage.jsx) that is modeled after AdminsCreatePage.jsx.
• There are stories and tests implemented modeled after the corresponding files in Frontiers.

If you have any questions about this issue feel free to ask me or any of the teaching staff about it!
