我怎样才能让这个功能重新启动？

Question

我有一个使用 Discord.JS 用 Node.JS 编写的 Discord BOT 我有一个在机器人上线时启动的功能

它包括从 API 获取数组：https://jacob.rede-epic.com/api/upcomingEvents 使用时间戳，它应该在消息发生前 10、5 和 1 分钟、发生时（确切小时 + 15 分钟，例如：08:15/09:15/10:15 等）以及何时发送消息结束（20 分钟后，例如：08:35/09:35/10:35 等）

我怎样才能重置整个系统？ 代码：

const { MessageEmbed } = require('discord.js');
const axios = require('axios');

class Jacob {
    constructor(client) {
        this.client = client;
    }

    async start() {
        const jacobContestsChannel = this.client.channels.cache.get('852596632591269968');
        let nextEventObject = null;
        let sentNotification = false;
        let sentNotification2 = false;
        let sentNotification3 = false;
        let sentNotificationActive = false;
        let sentNotificationFinished = false;

        const cropNames = [
            'Cactus',
            'Carrot',
            'Cocoa beans',
            'Melon',
            'Mushroom',
            'Nether wart',
            'Potato',
            'Pumpkin',
            'Sugar cane',
            'Wheat',
        ];

        setInterval(async () => {
            let upcomingEvents = [];
            let response = await axios.get('https://jacob.rede-epic.com/api/upcomingEvents');
            let request = response.data;

            for (let i in request) {
                upcomingEvents.push(request[i]);
            }

            if (nextEventObject == null) {
                nextEventObject = upcomingEvents[0];
            } else {
