Mongodb run $in on an array

Question

i am trying to do a simple query, which is based on array of objects. fieldA is an array of objects and my query looks something like this

const books = [
  {name: 'LOTR', author: 'J.R Tolkien'},
  {name: 'HP', author: 'JK. Rowling'},
  {name: 'Witcher', author: 'A. Sapkowski'}
];

const exists = await Book.exists({ fieldA: { $in: books } });

I am trying to see if the books in books array exist in database by implementing a search on fieldA which is an array of objects. The problem is that $in seems to take only one entity and it always returns false this way. Is there any way i can use $in but on array of objects?
