You can't "import" a chatbot in another one.
The best way to do this is to build a single bot on Botnation but in 2 parts and use the "contexts" on the IA panel to isolate the parts from each other with a unique context for each of them.
You can also start the chatbot in different sequences depending on the parts.
Need to know :
• Introduction to the Context
• Redirect to a specific sequence of a Messenger chatbot from a clickable link
