How to clear database after each integration test in NestJS and TypeORM?

I used TypeORMModule to provide config for the DataSource:

@Module({
  imports: [
    ConfigModule.forRoot({
      isGlobal: true,
      envFilePath: `.env.${process.env.NODE_ENV}`,
    }),
    TypeOrmModule.forRootAsync({
      inject: [ConfigService],
      useFactory: (config: ConfigService) => {
        return {
          type: 'postgres',
          // host has to be the container name of the database
          host: config.get<string>('POSTGRES_HOST'),
          port: parseInt(config.get('POSTGRES_PORT')),
          username: config.get<string>('POSTGRES_USER'),
          password: config.get<string>('POSTGRES_PASSWORD'),
          database: config.get<string>('POSTGRES_DB'),
          synchronize: true,
          entities: [User],
        };
      },
    }),
    UsersModule,
  ],
})

How do I go about clearing the database for each test?

I got dataSource from app.get(DataSource) and applied delete:

afterEach(async () => {
    const dataSource = app.get(DataSource);
    await dataSource.createQueryBuilder().delete().from(User).execute();
  });
