Hi,

I want to see, what's coming from outside to my SNS service in localstack like payload.
Where can I see it? I have set `DEBUG=1` but I still not see anything.
'Message': message,
        'SubscribeURL': req_data.get('SubscribeURL', [None])[0],
        'Timestamp': timestamp_millis(),
        'SignatureVersion': '1',
        
        
        'Signature': 'EXAMPLEpH+..',
        'SigningCertURL': 'https://sns.us-east-1.amazonaws.com/SimpleNotificationService-0000000000000000000000.pem'
    }
    if subject is not None:
        data['Subject'] = subject
    attributes = get_message_attributes(req_data)
    if attributes:
        data['MessageAttributes'] = attributes
    return json.dumps(data)
def create_sqs_message_attributes(subscriber, attributes):
    if not is_raw_message_delivery(subscriber):
        return {}
    message_attributes = {}
    for key, value in attributes.items():
        attribute = {
            'DataType': value['Type']
        }
        if value['Type'] == 'Binary':
            attribute['BinaryValue'] = value['Value']
        else:
            attribute['StringValue'] = str(value['Value'])
        message_attributes[key] = attribute
    return message_attributes
def get_message_attributes(req_data):
