How to get the id's for all documents without the data in a parsed collection in Firebase Firestore?

Question

I'm trying to get all the ids of all documents from a parsed collection without being charged for getting the document data. Will I be charged for receiving the data if I use this code below?

  db.collection("owners").get().then(function(querySnapshot) {

      });
  });
