Send empty HTTP 200 response

I am using the slack api. According to the docs, we need to send back an "empty HTTP 200 response to the original request" in order to confirm we received the command in Xano. Otherwise, Slack posts an "error" or "null" message in the channel.

If I return nothing on Xano, a message is still shown with value = null. But, I dont want to show the message at all. Hence, I need send back only the empty http 200 response.

How can I do so?

Thanks.
