How to use sqlite to store the cooldown of a command?

I want to try to store my command cooldown in any sort of storage, I think sqlite will be good, but I don’t know how to implement it for a cooldown.. I was checking one guide here https://anidiots.guide/coding-guides/sqlite-based-points-system/#you-get-points-and-you-get-points-and-everybody-gets-points, it’s for storage points and levels.. Unfortunately I’m not able edit this example into my needs, to store the cooldown for each user.

'use strict';

const SQLite = require("better-sqlite3");
const sql = new SQLite("./cooldowns.sqlite");

const humanizeDuration = require('humanize-duration');

// Require the necessary discord.js classes
const { Client, Intents, Collection } = require('discord.js');
const config = require("./config.json");
const { MessageEmbed } = require('discord.js');
const cooldowns = new Map();
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

client.on('ready', () => {
  const table = sql.prepare("SELECT count(*) FROM sqlite_master WHERE type='table' AND name = 'scores';").get();
  if (!table['count(*)']) {
    // If the table isn't there, create it and setup the database correctly.
    sql.prepare("CREATE TABLE scores (id TEXT PRIMARY KEY, user TEXT, guild TEXT, points INTEGER, level INTEGER);").run();
    // Ensure that the "id" row is always unique and indexed.
    sql.prepare("CREATE UNIQUE INDEX idx_scores_id ON scores (id);").run();
    sql.pragma("synchronous = 1");
    sql.pragma("journal_mode = wal");
  }
  // And then we have two prepared statements to get and set the score data.
  client.getCooldown = sql.prepare("SELECT * FROM scores WHERE user = ? AND guild = ?");
  client.setCooldown = sql.prepare("INSERT OR REPLACE INTO scores (id, user, guild, points, level) VALUES (@id, @user, @guild, @points, @level);");
  
  client.user.setActivity("thinking...", { type: 'PLAYING' });
  console.log('Bot is online!')
});

client.on("messageCreate", message => {
    if (message.author.bot) return;
    // This is where we'll put our code.
    if (message.content.indexOf(config.prefix) !== 0) return;
  
    const args = message.content.slice(config.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();
  
    if(command === 'mycommand') {
    const cooldown = cooldowns.getCooldown(message.author.id);
    if (!cooldown) {
        cooldowns = {
          id: `${message.author.id}`,
          user: message.author.id,
          cooldown: 0
        }
      }
    if (cooldown) {
        const remaining = humanizeDuration(cooldown - Date.now(), { round: true }, { units: ["d","h","m","s"] });
    
        message.reply(`Your cooldown is. ${remaining}`)
        return;
    }  
      async function main() {
      const messages = await message.channel.messages.fetch({ limit: 1 });
      const lastMessage = messages.last();
      const isValidDate = (dateString) => new Date(dateString).toString() !== 'Invalid Date'
      if(isValidDate(lastMessage.content) == false && lastMessage.content !== 'mycommand')
      message.reply("I need your date of birth!.")
      if(lastMessage.content === 'mycommand')
      message.reply("Please provide me your date of birth.")
      if(isValidDate(lastMessage.content) == true && lastMessage.content !== 'mycommand') {
      cooldowns.set(message.author.id, Date.now() + 604800000);
      message.reply("Check your DMs.")
      message.react("emoji"); //react with emoji to the issued command
      const predictions = ["Prediction 1", "Prediction 2", "Prediction 3", "Prediction 4", "Prediction 5", "Prediction 6", "Prediction 7"]
      const randomprediction = predictions[Math.floor(Math.random() * predictions.length)];
        const prediction1 = new MessageEmbed()
          .setColor('#ff7518')
        .setAuthor(client.user.username, client.user.displayAvatarURL())
          .setTitle(`Weekly message` + lastMessage.author.username + `#` + lastMessage.author.discriminator) 
        .setDescription(randomprediction);
        message.author.send({ embeds: [prediction1] });
        var random = Math.random()
        if (random < 0.9) {
        message.author.send("Congrats! You received this message " + '<@' + message.author.id + '>!')
        message.channel.send('Congrats again! ' + '<@' + message.author.id + '>'); 
        }
        setTimeout(() => cooldowns.delete(message.author.id), 604800000);
        client.setCooldown.run(cooldowns);
      }
  }
}

The problem is I don’t know how to edit the sql params, I never used sqlite/anything else before and have 0 experience with it. All I want is to store command in some sort of storage, but I don’t know where to start. Any help will be much appreciated!
