- * Logout button to submit a form post request to the `logout_url` prop.
- * Usage is intended for dash-deployment-server authentication.
- *
- * DDS usage:
- *
- * `dcc.LogoutButton(logout_url=os.getenv('DASH_LOGOUT_URL'))`
- *
- * Custom usage:
- *
- * - Implement a login mechanism.
- * - Create a flask route with a post method handler.
- * `@app.server.route('/logout', methods=['POST'])`
- *   - The logout route should perform what's necessary for the user to logout.
- *   - If you store the session in a cookie, clear the cookie:
- *   `rep = flask.Response(); rep.set_cookie('session', '', expires=0)`
- *
- * - Create a logout button component and assign it the logout_url
- * `dcc.LogoutButton(logout_url='/logout')`
- *
- * See https://dash.plotly.com/dash-core-components/logout_button
- * for more documentation and examples.
+ * LogoutButton component to handle user logout.
+ * Sends a POST request to the provided `logoutUrl` when clicked.
