It would be nice to add a feature to the design tab in which we can increase, decrease, or eliminate the shadow around the bot when it is embedded or on a standalone page. There is something slightly off about the iframe configuration that always cuts the shadow off at the bottom. This essentially defeats the purpose of that dropshadow. In some cases though, it would be nice just to eliminate it all together.
The cut of shadow is because the embed element ends there.
If you are embedding the bot in a webpage, you just need to leave enough space around the embed so that it doesn’t overlap the shadow.
If you want to configure the shadow in your embeds, you can change the CSS box-shadow property for it
