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.
for topic_arn in SNS_SUBSCRIPTIONS:
        SNS_SUBSCRIPTIONS[topic_arn] = [
            sub for sub in SNS_SUBSCRIPTIONS[topic_arn]
            if sub['SubscriptionArn'] != subscription_arn
        ]
def _get_tags(topic_arn):
    if topic_arn not in SNS_TAGS:
        SNS_TAGS[topic_arn] = []
    return SNS_TAGS[topic_arn]
def do_list_tags_for_resource(topic_arn):
    return _get_tags(topic_arn)
def do_tag_resource(topic_arn, tags):
    existing_tags = SNS_TAGS.get(topic_arn, [])
    tags = [
        tag for idx, tag in enumerate(tags)
        if tag not in tags[:idx]
    ]
    def existing_tag_index(item):
        for idx, tag in enumerate(existing_tags):
            if item['Key'] == tag['Key']:
                return idx
        return None
    for item in tags:
        existing_index = existing_tag_index(item)
        if existing_index is None:
            existing_tags.append(item)
        else:
            existing_tags[existing_index] = item
    SNS_TAGS[topic_arn] = existing_tags
def do_untag_resource(topic_arn, tag_keys):
