Can I build my own Messenger UI using Intercom's API?

Hi intercom,
In order to integrate with other chat service.
We're evaluating the possibility of replacing the Messenger widget with our own chat UI, backed by the conversation API / or intercom-node

I found this post before: 

  • You will need to handle apps inserted into the messenger and conversations.
  • You will miss out on a lot of the features offered by Operator.

 

May I know what exactly will miss / break if connecting via API ?
this is what i found so far: 

1. Canvas Kit apps in conversations

2. Fin replies: does Fin's answer arrive as a normal `comment` part (plain text/HTML we can render) ?

3. Read/seen state

Anything else that silently breaks in a custom UI when Operator/Workflows run ?

Or is there a guidance in document regarding this approach?

Thanks
