We are designing an API to support manual accept/reject of follow requests in #BotKit. Which of the below two approaches seems better?

Returning true or false in the onFollow event

bot.onFollow = async (session, follower) => {
  // Accept follows requests from non-bot accounts:
  return follower instanceof Person;
};

Accepting a followRequest object as the third parameter in the onFollow event and calling the accept() or reject() method

bot.onFollow = async (session, follower, followRequest) => {
  // Accept follows requests from non-bot accounts:
  if (follower instanceof Person) await followRequest.accept();
  else await followRequest.reject();
};
