If you're running the demo, you can use the share link and not give it to anyone else. Or you can give link only to specific person(s). Note: Right now there's no way to reset the share link, but you can Export the bot and Import it to a new bot to reset the share link by deleting the old bot (it will delete the share link too). Alternately, you can spin up a website and embed the bot as a widget or w/in a div etc.
