Does this seem like a sensible approach to managing authentication state? I'm using Cognito via Amplify and have an authentication context that provides the user to the rest of the application. I need to perform side effects in the authentication context and on the page, so I'm exposing a React Query mutation from the context provider that facilitates this... * CODE IN THREAD * Thanks 🙂

export const AuthenticationContextProvider = ({
  children,
}: AuthenticationContextProviderProps) => {
  const [user, setUser] = useState<CustomCognitoUser>();

  const { isLoading: isGettingAuthenticatedUser } = useQuery<CustomCognitoUser>(
    "getAuthenticatedUser",
    () => authenticationService.getAuthenticatedUser(),
    {
      onSuccess: (user) => {
        setUser(user);
      },
    },
  );

  const signInMutation = useMutation<
    CustomCognitoUser,
    Error,
    AuthenticationCredentials
  >(
    ({ emailAddress, password }: AuthenticationCredentials) =>
      authenticationService.signIn({
        emailAddress,
        password,
      }),
    {
      onSuccess: (user) => {
        setUser(user);
      },
    },
  );
