How to use the aioboto3.resource function in aioboto3

async def test_getting_resource_cm(event_loop):
    """Simple getting of resource."""
    aioboto3.DEFAULT_SESSION = None

    async with aioboto3.resource('dynamodb', loop=event_loop, region_name='eu-central-1') as resource:

    resource = aioboto3.resource('dynamodb', loop=event_loop, region_name='eu-central-1')
    assert isinstance(resource.meta.client, AioBaseClient)
    await resource.close()

async def _initialize(self):

        self.http = aiohttp.ClientSession()
        self.dynamo = aioboto3.resource('dynamodb', region_name=DYNAMO_REGION)

        log.info("DDB client initialized")
