Problems incrementing a field of an object inside an array in firestore [duplicate]

In firestore, i have a collection called questions of documents with the following structure

{ category : "animals",
topics : [ {title :"habitats", votes: 1}, {title :"pets", votes: 5} ] }

I want to build a function that receives title as parameter, and increments votes by one, with no success.

I am trying things like :

const docRef = doc(db, "questions", id);

await updateDoc(docRef, {
        topics: {
          name: topicName,
          vote: increment(1),
        },
      });

//with arrayUnion

await updateDoc(docRef, {
        topics: arrayUnion{
          name: topicName,
          vote: increment(1),
        },
      });

But the only thing I do is updating the array replacing the two objects with just a new one, or adding a new object to the two existing ones.
