I need help with model integration for my specific layout using Sequelize

[ZoomGC]

Hello there, I am using Sequelize with node.js, Redis (unimportant), and discord.js (you'll see discord.js code primarily in /src/index.js) with the file structure:

|src
|-index.js
|-.env
|-Commands
|--Community
|--Moderation(empty)
|--Other
|-functions
|--BypassStartup
|---db.js
|-models
|--index.js
|---table1
|---table2
|---table3

my /src/index.js is this:

const { Client, GatewayIntentBits, EmbedBuilder, PermissionsBitField, Permissions, MessageManager, Embed, Collection } = require(`discord.js`);
const fs = require('fs');
const { Database } = require("./functions/BypassStartup/db");

const client = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent] }); 

client.commands = new Collection();


require('dotenv').config();
let db = new Database(); // DATABASE INIT

const functions = fs.readdirSync("./functions").filter(file => file.endsWith(".js"));
const eventFiles = fs.readdirSync("./events").filter(file => file.endsWith(".js"));
const commandFolders = fs.readdirSync("./commands");

(async () => {
    for (file of functions) {
        require(`./functions/${file}`)(client);
    }
    client.handleEvents(eventFiles, "./events");
    client.handleCommands(commandFolders, "./commands");
    client.login(process.env.token)
})();```


/src/functions/BypassStartup/db.js (My DB file)

const { Sequelize } = require("sequelize");
const { RedisHandler } = require("../BypassStartup/RedisClient");

class Database extends Sequelize {
constructor(options = {}) {
const { POSTGRES_URI } = process.env;
const sequelizeOptions = {
dialect: 'postgres'
};
super(POSTGRES_URI, sequelizeOptions);

    this.RedisHandler = new RedisHandler();


    this.boot();
}

boot() {
    this.authenticate()
        .then(() => console.log("[DATABASE] Successfully connected"))
        .catch((error) => console.error(`[DATABASE] Failed to connect\n${error.stack}`));
    this.RedisHandler.redisClient.connect()
        .then(() => console.log("[REDIS] Successfully Connected"))
        .catch((error) => console.error(`[REDIS] Failed to connect\n${error.stack}`))
}

}

module.exports = { Database };``` - I need to know how to pass the next file INTO this to allow models to be used, or some other way to put my models into my object "db" (instance of class Database which extends sequelize) in /src/index.js

/src/models/sequelizer/index.js (Unfinished)

const fs = require('fs');
const path = require('path');
//const {Database} = require("../../functions/BypassStartup/db");
const basename = path.basename(__filename)



fs
    .readdirSync(__dirname)
    .filter(file => {
        return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
    })
    .forEach(file => {
        const model = require(path.join(__dirname, file))(db)
    })

Any help would be greatly appreciated.
Thanks in advance.
