Modifying the redirect page after login is simple. Just check authenticated
method available inside app/Http/Controllers/Web/Auth/LoginController
and replace return redirect()->intended();
line with one of the following:
// to redirect to custom url (can be any url)
return redirect()->to("your url here");
//or
// to redirect to specific Vanguard route
// with name that is already defined for that route
return redirect()->route("route_name_here");
