Incremental data for attachments in messages and replies

Following up with the previous reply, actually I was able to get attachments incrementally by using below mentioned query, by fetching attachments at descendants replies level. So we are good here. But I noticed 2 things:

1. Giving kudos to a message or reply is not updating conversationLastPostTime.
2. Editing a reply is also not updating conversationLastPostTime.

Can you please guide us on how to get edited message or reply and how to get updated kudos count in incremental data.

query Replies {
  messages(
    constraints: {conversationLastPostTime: {gte: "2024-10-23T09:04:18.439+01:00", lte: "2025-01-01T00:00:00.000+00:00"}, depth: {eq: 0}}
    last: 1000
  ) {
    edges {
      node {
        id
        descendants {
          edges {
            node {
              id
              body
              board {
                id
              }
              attachments {
                edges {
                  node {
                    id
                    url
                  }
                }
              }
              author {
                id
                login
              }
              depth
              kudos {
                totalCount
              }
              postTime
              viewHref
            }
          }
        }
      }
    }
    totalCount
  }
}
