typescript type when I pass an onSuccess callback to my custom hook

Hey guys, I have this custom hook and I want to be able to pass a onSuccess callback to it, but I don't know which type should I use here ? I have done this but if the type returned from the function change i will have to change the type, is there some more opitmal?

export const usePatchCampaign = ({
  onSuccess,
}: {
  onSuccess: (param: ExperimentV1<ExclusionGroupWithArchived> | undefined) => void;
}) => {
  return useMutation({
    mutationFn: () => {}
    onSuccess,
  });
};

export const usePatchCampaign = ({
  onSuccess,
}: {
  onSuccess: (param: ExperimentV1<ExclusionGroupWithArchived> | undefined) => void;
}) => {
  return useMutation({
    mutationFn: () => {}
    onSuccess,
  });
};
