React Router v6 child route not rendering

With React Router v6 I want to render the callback page. Although I’m not able to get the output from the element prop in my screen. I’m only getting the output from out and always a blank screen or a 404 for the callback page. What am I missing with the new React Router?

const App: React.FC = () => (
  <>
    <GlobalStyle />
    <Suspense fallback={<Loading fullScreen />}>
      <Routes>
        <Route path="/" element={<PrivateRoute component={Home} />} />
        <Route path="/login" element={<PublicRoute component={Login} />} />
        <Route path="/auth/*" element={<p>auth</p>}>
          <Route path="callback" element={<p>callback</p>} />
        </Route>
      </Routes>
    </Suspense>
  </>
);

const App: React.FC = () => (
  <>
    <GlobalStyle />
    <Suspense fallback={<Loading fullScreen />}>
      <Routes>
        <Route path="/" element={<PrivateRoute component={Home} />} />
        <Route path="/login" element={<PublicRoute component={Login} />} />
        <Route path="/auth/callback" element={<p>callback</p>} />
      </Routes>
    </Suspense>
  </>
);

Also using an Outlet doesn’t seem to solve the problem..

const App: React.FC = () => (
  <>
    <GlobalStyle />
    <Suspense fallback={<Loading fullScreen />}>
      <Routes>
        <Route path="/" element={<PrivateRoute component={Home} />} />
        <Route path="/login" element={<PublicRoute component={Login} />} />
        <Route path="/auth/*" element={<><p>auth</p><Outlet /></>}>
          <Route path="callback" element={<p>callback</p>} />
        </Route>
      </Routes>
    </Suspense>
  </>
);

The BrowserRouter is in my Root component, which is rendering App.
