If you feel that the immediate responses provided by the bot are a bit "inhuman", use the typing widget to create a more natural feel.
The typing widget simulates the typing dots from the user's point of view. You can set the typing widget to appear for anywhere from 1 to 20 seconds!
Place this widget before widgets like the attachment widget and the video widget to let your users know something is coming.
It's also a good idea to put this in between widgets so it gives the user time to read each widget.
