The documentation mentions an excluded_response_id field but the param doesn't seem to be available. In fact it's not showing here.
My use case is to retrieve only the responses that I have not seen yet (aka new responses) and this flag makes perfect sense.
For example:
self.typeform.responses.list(form_id, excludedResponseIds=["<id>",])
The response I get back is
TypeError: list() got an unexpected keyword argument 'excludedResponseIds'
