body: <p>I am trying to create  airflow dag using python to copy a file one S3 bucket to another S3 bucket.</p>
  <p><strong>My code</strong></p>
  <pre><code>from airflow import DAG
  from datetime import datetime, timedelta
  from utils import FAILURE_EMAILS
  
  from airflow.providers.amazon.aws.operators.s3_copy_object import S3CopyObjectOperator
  default_args = {
      'owner': 'airflow',
      'depends_on_past': False,
      'start_date': datetime(2020, 1, 1),
      'email': FAILURE_EMAILS,
      'email_on_failure': False,
      'email_on_retry': False,
      'retries': 0,
      'retry_delay': timedelta(minutes=5)
  }
  
  dag = DAG(
      'S3_COPY_S3',
      default_args=default_args,
      catchup=False,
      schedule_interval=None,
      max_active_runs=1
  )
  
  copy_step = S3CopyObjectOperator(
     source_bucket_key='source_file',
     dest_bucket_key='dest_file',
     aws_conn_id='aws_connection_id',
     source_bucket_name='source-bucket',
     dest_bucket_name='dest-bucket',
     dag=dag
  )
  </code></pre>
  <p>Is this correct? Can you someone please verify</p>
