new QueryClient instantiated in a function component

Hi, so I want to trigger toasts on errors, and the toasts can only be controlled through hooks. In this case, instead of instantiating the query client globally, I made a wrapper rq provider which has access to the toast provider:
export const RQClientProvider = ({
  children,
}: {
  children: React.ReactNode;
}) => {
  const toast = useToastController();
  const queryClient = new QueryClient({
    defaultOptions: {
      queries: {
        retry: 1,
        refetchOnWindowFocus: false,
        staleTime: 10_000,
      },
    },
    queryCache: new QueryCache({
      onError: (error_: any) => {
        const error = error_ as AxiosError;
        toast.show("Error", {
          customData: {
            preset: "error",
          },
          message:
            error.response?.status === 404 ? "Not found" : error.message,
        });
      },
    }),
  });

  return <QueryClientProvider client={queryClient}>{children}</QueryClientProvider>;


So my question is: is it still okay to instantiate a client in this way? There's only 1 way to trigger this provider rerender - which is by changing the theme (as my theme provider and toast provider are coming from the same library)
