Not able to delete document from firestore database v9 – Reactjs

There is a collection users and inside user there is a document userID and inside this document there is another collection favourite and inside this collection , there is id’s of saved favourite data favouriteId.

So i want to delete that data inside favourite colletion.

My db look likes:-
users(collection)>userID(document)>favourite(collection)>favouriteId(document)

Here is my code for that:

  const deleteDoc = async (id) => {
    const userRef = collection(db, "users");
    const favRef = collection(
      userRef,
      `${firebaseAuth?.currentUser?.uid}/favourite`
    );
    const favId = doc(favRef, id);
    await deleteDoc(favId);
  };

favouriteId=id ,
userId=firebaseAuth?.currentUser?.uid

I use firebase v9.

    your code is Most of correct you just need some changings in code like that

    const deleteDocu = async (userId, favouriteId) => {
const userRef = collection(db, "users");
const favRef = collection(userRef, userId, "favourite");
const favId = doc(favRef, favouriteId);
await deleteDoc(favId);
};

    You are naming your function in the same way as the Firebase function.

    Just change the function name

      const deleteDocu = async (id) => {
    const userRef = collection(db, "users");
    const favRef = collection(
      userRef,
      `${firebaseAuth?.currentUser?.uid}/favourite`
    );
    const favId = doc(favRef, id);
    await deleteDoc(favId);
  };
