User commit additions and deletions

Hey. I am interested in querying GraphQL to find the commits myself and a group of friends have made. I can do so with the following query (note I am aware this is a basic query but I have simplified for illustrative purposes):

  user(login: "login") {
    contributionsCollection {
      commitContributionsByRepository {
        repository {
          name
        }
        contributions(last: 100) {
          nodes {
            commitCount
          }
        }
      }
    }
  }
}

This provides the number of commits on a certain day and which repo they were made to.

I would also like to also see the number of additions and deletions for each contribution.

How is this possible?

Thanks
