          request. For each stream set of fields will be different and we get those fields from stream's schema.
          Also each nested object, like `workspace`, or list of nested objects, like `followers`, also by default returns
          those 3 fields mentioned above, so for nested stuff we also need to specify fields we want to return and we
          decided that for all nested objects and list of objects we will be getting only `gid` field.
          Plus each stream can have it's exceptions about how request required fields, like in `Tasks` stream.
