In a relation subquery, how to reference parent column?

    const result = await db.query.author.findFirst({
      where: (author) => eq(author.slug, params.slug),
      with: {
        collections: {
          with: {
            collection: {
              with: {
                books: {
                  with: {
                    book: {
                      with: {
                        authors: {
                          where: (authorBook, { ne }) => ne(authorBook.authorId, author.id),
                          with: {
                            author: true
                          }
                        }
                      }
                    }
                  }
                },
                authors: {
                  with: {
                    author: true
                  }
                }
              }
            }
          }
        }
      }
    });

    const result = await db.query.author.findFirst({
      where: (author) => eq(author.slug, params.slug),
      with: {
        collections: {
          with: {
            collection: {
              with: {
                books: {
                  with: {
                    book: {
                      with: {
                        authors: {
                          where: (authorBook, { ne }) => ne(authorBook.authorId, author.id),
                          with: {
                            author: true
                          }
                        }
                      }
                    }
                  }
                },
                authors: {
                  with: {
                    author: true
                  }
                }
              }
            }
          }
        }
      }
    });
