I'll add a button at the bottom-right side to go back to the previous page. To ensure that the page receives the same information as when it was loaded after the login page, we'll use Next.js's router to handle the navigation.

Let's update the RoleBasedAccessControl component to include this new button:

Now, let's update the main page component to ensure it passes the necessary information when navigating to the role-based access control page:

Now, let's update the RoleBasedDashboard component to include the new button:

Finally, let's update the role-based access control page to handle the user's authentication state:

These changes will add a "Back" button to the role-based access control page and ensure that the user's authentication state is maintained when navigating between pages. The main page now includes a button to navigate to the role-based access control page, and the role-based access control page checks for authentication before rendering its content.

The "Back" button uses the browser's history, so it will return to the previous page (which should be the main dashboard) with the same state as before. If you need to pass specific data between pages, you might want to consider using state management solutions like React Context or a state management library.

You're right, and we need to fix this issue. Let's modify our approach to ensure the back button takes the user to the correct previous page, which should be the dashboard.

Let's make the following changes:

1. Update the RoleBasedAccessControl component to use a custom back function instead of router.back().
2. Modify the main page to pass the user's role to the role-based access control page.
3. Update the role-based access control page to handle the navigation based on the user's role.

First, let's update the RoleBasedAccessControl component:

Now, let's update the main page to store the user's role in localStorage when navigating to the role-based access control page:

Finally, let's update the role-based access control page to handle the navigation based on the user's role:

These changes should fix the issue with the back button. Here's a summary of what we've done:

1. We now store the user's role in localStorage when navigating to the role-based access control page.
2. The back button in the role-based access control page checks for the stored role and navigates accordingly.
3. We clear the stored role when the role-based access control page is loaded to prevent stale data.
4. If there's no authenticated user, we redirect to the login page.

This approach ensures that the back button will take the user to the correct dashboard based on their role, or to the login page if they're not authenticated. The role-based access control page now also has a title for better user experience.
