How to make node-cron control?

Question

Node.js

Hi all.
The question
is something like this code:

const cron = require('node-cron')
const {Post} = require('../schems/postSchema');
const {User, update} = require('../schems/userSchema')
const cronUpdate = cron.schedule('58 23 * * *', update(),{timezone:'Europe/Kiev'});
const cronSend = cron.schedule('59 23 * * *', send() ,{timezone:'Europe/Kiev'});
async function send(){
    const usersArr = await User.find();
    const postArr = await Post.find();
if (usersArr){
        const day1Users = usersArr.filter(user=>user.status === 'day1');
        const day2Users = usersArr.filter(user=>user.status === 'day2');
        const day3Users = usersArr.filter(user=>user.status === 'day3');
        const day7Users = usersArr.filter(user=>user.status === 'day7');
        if (day1Users){
            const day1PostArr = postArr.filter(postage=>postage.datePost == 1 )
                    day1PostArr.map(msg=>{
                        day1Users.map(user=>{
                            const send = cron.schedule(`${msg.second} * ${msg.hour} ${user.dateNow+1} * *`,()=>{
bot.sendMessage(user.userId,msg.post , {parse_mode: 'Markdown', disable_web_page_preview: true})
                            })  
                        })
                    })
}
