Project Management Sidebar - Copy this React, Tailwind Component to your project

Design a collapsible sidebar for the project management tool. The sidebar should expand and collapse. The application should always have a top panel that does not collapse, and there should always be a user icon and an Exit button on the top panel. There is also a theme toggle button. When scrolling the page, the top bar should not disappear, and should always be fixed. The sidebar should disappear completely in the mobile version, and only the hamburger button should remain on the top, fixed panel. It should support dark and light themes.
