-- Use one of the following lenses to modify other fields as desired:
--
-- * 'gcfccNextToken' - An enumeration token that when provided in a request, returns the next batch of the results.
--
-- * 'gcfccBeforeCommitId' - To establish the directionality of the comparison, the full commit ID of the 'before' commit.
--
-- * 'gcfccMaxResults' - A non-negative integer used to limit the number of returned results. The default is 100 comments, and is configurable up to 500.
--
-- * 'gcfccRepositoryName' - The name of the repository where you want to compare commits.
--
-- * 'gcfccAfterCommitId' - To establish the directionality of the comparison, the full commit ID of the 'after' commit.
