Use class container-fluid instead of container.

See the sizes for the container classes: https://getbootstrap.com/docs/5.0/layout/containers/#how-they-work

import NavigationBar from "./components/NavigationBar"
import ListGroup from './components/ListGroup';

function App() {
    return (
        <div>
            <NavigationBar />
            <div className="container-fluid">
                <div className="row align-items-start">
                    <div className="col-md-auto">
                        <ListGroup />
                    </div>
                    <div className="col-lg-auto">
                        Feed
                    </div>
                </div>
            </div>
        </div>
    );
}

export default App;
