Which method should I use instead of onSuccess

[Michael-indochat]

this is example code,
which method should I use instead of onSuccess?

  const mutation = useMutation({
    mutationFn: postTodo,
    onSuccess: () => {
      alert("fetch success")
    },
  })

callbacks of mutations are NOT deprecated and can still be used.

Is this usage correct?
Let me judge whether the mutation is executed correctly.

const mutation = useMutation({
    mutationFn: postTodo,
});

const submitEvent = e => {
  e.preventDefault();
  mutation.mutate();
  try {
    console.log("success");
  } catch (error) {
    console.log("error");
  }
};
