Sending whispers with my IRC bot

Chat and IRC

ChatRaids bot = new ChatRaids();
bot.setVerbose(true);
bot.connect("irc.twitch.tv", 6667, "oauth:XXXX");
bot.joinChannel("#twitchraidstwitch");
sendMessage("#twitchraidstwitch", "CAP REQ :twitch.tv/membership\r\n");
sendMessage("#twitchraidstwitch", "CAP REQ :twitch.tv/tags\r\n");
sendMessage("#twitchraidstwitch", "CAP REQ :twitch.tv/commands\r\n");

^ That just sends the message into chat and doesn’t work.
