How to use the react-native-sqlite-storage.enablePromise function in react-native-sqlite-storage

public open(): Promise {
    SQLite.DEBUG(true);
    SQLite.enablePromise(true);
    let databaseInstance: SQLite.SQLiteDatabase;

    return SQLite.openDatabase({
      name: DATABASE.FILE_NAME,
      location: "default"
    })
      .then(db => {
        databaseInstance = db;
        console.log("[db] Database open!");

        // Perform any database initialization or updates, if needed
        const databaseInitialization = new DatabaseInitialization();
        return databaseInitialization.updateDatabaseTables(databaseInstance);
      })
      .then(() => {
        this.database = databaseInstance;
