Remove tags

[CCLJ]

I'm not sure if I'm using the untag_objects method right or not, but it isn't working. Using it like this:
Ontraport.untag_objects :contact, { ids: user_id, remove_list: tag }.

I took a look at the source code and the implementation of the method seems to have a typo:

def self.untag_objects object_type, object:, tag:
  objects_call :delete, object_type, endpoint: '/objects/tag', data: params
end

The argument params is not defined in the header.
