Hi all, I am an extreme newbie at this so please forgive the dumb question. After a user submits input, I would like my bot to say something like "Processing request..." while it works on sending the response to the user's input. The reason is because the default loading elipses don't usually show up until several seconds after the user has submitted their input. I would like them to see that it's working on the request as soon as possible. How can I do this?
