Unable to get the link rel='delta' when using getEntities() with Delta Service

Hi All,

I have a delta service in SAP OData v2. I am getting the entities without any problem with the standard

entity = getattr(self.service.entity_sets, entity_name)
request = entity.get_entities()
response = await request.async_execute()

The thing is that the returned ListWithTotalCount object that is returned as response does not serialize the non-entry xml elements.
There is however a very important part of the raw response that I cannot get to with help of the library. At the very end of the raw response (with standard requests library) there is an element

< link rel="delta"
href="AttrOfZC_SST_BUSINESSENTITY?&!deltatoken='DELTATOKEN'" >

Am I missing something ? I couldnt find a way to get to the raw response with pyodata through example or source code analysis. Could someone please point me to the right direction? I would really like to avoid having to fetch DeltaLinks in a separate request while the first one already fetches all I need.

Thanks!
