Redirect to panel with notification

Does anyone know how to redirect from a controller to a panel with a notification?

return redirect('/admin')->with('success', 'My success message.');

return redirect('/admin')->with('success', 'My success message.');

return redirect('/admin')->with('success', 'My success message.');

return redirect('/admin')->with('success', 'My success message.'); doesn't work.

Cheers

Solution

Solution from Mark Chaney: If you do a notificaiton and then immediately do a redirect, it will show on the next page.
