please answer whatever asked in the questions. Description: You have been asked to build an admin portal that will allow your company internal employees to access the portal and perform admin functions on behalf of company clients.

Here are additional details:

(a) Admin portal is accessible only on company network to only company employees that have the "ADMIN" role. (b) Access to the links is role based i.e. only authenticated internal employees with "ADMIN" role are able to access the portal and what links you can access once on the portal is determined based on what other roles you have. So, same link will not be visible to other admin who doesn't have appropriate role to access the link. (c) There are five catagories of applications and 5 admin roles for each category. Here are the details:
