how to handle the RedirectIfAuthenticated middleware in API requests

someone send a request to login endpoint with bearer token and after that user redirected to the dashboard

what is the appropriate response I should respond to?

    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {

            if ($request->wantsJson()) {
                return response()->json(); // ?
            }


            return redirect('/');
        }

        return $next($request);
    }
