Cast or cancel a vote

You can cast or cancel a vote by passing PollVoteEvent as an argument to a parameter when calling the votePoll() method. Use the optionIds property of the votePoll() method to update the user's final vote choice for a poll. This overrides previous vote actions, so to update previous votes, pass new pollOptionIds as a parameter. To cancel votes, pass an empty list as pollOptionIds.

// To apply the vote result to the poll, You need to take the following actions.
// 1. Find a poll by pollVoteEvent.messageId and pollVoteEvent.pollId.
// 2. Call userMessage.poll.applyPollVoteEvent(event: PollVoteEvent).

channel.votePoll(pollId: poll.pollId, pollOptionIds: [poll.firstOptionId]) { event, error in

}
