Cannot access to the db property of the instance SQLiteSessionStorage

I am learning the Shopify app development, but I got a problem when I followed the training course with NodeJS (https://shopify.dev/apps/getting-started/build-app-example/backend)

When we want to instanciate the class SQLiteSessionStorage like that :

const dbFile = join(process.cwd(), "database.sqlite");
const sessionDb = new SQLiteSessionStorage(dbFile);
// Initialize SQLite DB
QRCodesDB.db = sessionDb.db;
QRCodesDB.init();

An error is raised because the attribute .db of SQLiteSessionStorage is private :

export declare class SQLiteSessionStorage implements SessionStorage {
    private filename;
    private options;
    private db;
    private ready;
    constructor(filename: string, opts?: Partial

I don't know how to resolve this issue. Can someone help me ?

I create an issue in GitHub on the couse repository ([https://github.com/Shopify/shopify-app-examples/issues/136](https://github.com/Shopify/shopify-app-examples/issues/136))

Maybe it's a mistake from me, but I am blocked ...

Thank you very much in advance !

Respectfully,
