Seems like there is little to no examples on how to customize the bot (ex. make the messages have a bubble-like style like Messenger) or make it adjustable based on the size of the website window. Do we have more resources on that?

We are currently reworking the webchat to allow better customization. In the mean time you can have a look at this: https://discord.com/channels/1108396290624213082/1108396291060408352/1131141650450759772
