Description

For easier ops debugging capability, we need to create a preview page of the Quiz Exercise in the app

Delivery

• [ ] add field "isAdmin": false in the registered_user when registering
• [ ] add logic to check user's isAdmin in the setting page & display Lihat Bebras Task button if isAdmin == true don't forget to hide the button back when isAdmin == false
• [ ] add a page of ListView with the item's title from doc.id
