Is your feature request related to a problem? Please describe.
instead of scrolling all the way up ,adding a button that would scroll to directly navbar when someone reaches end of page.

Describe the solution you'd like
a scroll up button

No file or test is named. Start by locating the page component and navbar in the React application, then check how page scrolling is handled. Done means a visible scroll-up button appears when the user reaches the end of the page and returns them directly to the navbar.
