So larger chatbots can be built and triggered by trigger from one chatbot to the other

If we implement the ability to choose more than one CHATBOT per integration, this could solve the problem. We have a major chatbot with the start connected on the flow, and the others will be used just with triggers (start is not connected)

It also help for example to reuse CHATBOT blocks.

On a ecommerce CHATBOT, we can have a Chatbot for category, and simple copy and paste. Another CHATBOT with all checkout.
