Is there a way to update the likes and replies with firebase firestore?

I have reached that moment when I press on like on a single comment but I have only the reference to the document of the whole post , so I don't have a reference to the comments itself. I also reached the comment with the find method of the arrays but it's not a reference its the comment itself.

Thanks in advance, I am thinking I just have to reconsider how i structure my DB using firestore?

const addLikeToComment = async (
  postID: string,
  commentID: string,
  userID: string
): Promise<void> => {
  const currentPost = await getPostById(postID)
  const currentPostDocId = currentPost[0].docID!
  const currentPostRef = doc(db, 'posts', currentPostDocId)

  const commentToAddLikeTo = currentPost[0].comments.find(
    (currComment) => currComment.commentID === commentID
  )
  console.log(commentToAddLikeTo)
  if (!commentToAddLikeTo?.likes.includes(userID)) {
    await updateDoc(currentPostRef, {
        // add the like to comments - currentComment - likes array inside it push the userID
    })
  } else {
    await updateDoc(currentPostRef, {
        // remove the like
    })
  }
}
