Reply in thread using ResponseURL

[Albert221]

_, _, _, err = client.SendMessage(
    payload.Channel.ID,
    slack.MsgOptionResponseURL(payload.ResponseURL, slack.ResponseTypeInChannel),
    slack.MsgOptionTS(payload.Message.ThreadTimestamp),
    slack.MsgOptionText(reply, false),
)

This is my code. The MsgOptionTS sets the thread_ts, but it's not used later. I need it to send a message in thread: https://api.slack.com/interactivity/handling#publishing_in_thread
