Chatbox development.

Chatbox development continues to be a rapidly growing element on many platforms with some posts suggesting "the chatbot market is projected to account for $1.23 billion by the year 2025".

I'm wondering if anyone can steer me in the right direction. I am wondering if there are any initiatives for chatbox development similar to what has been done for drupal 8/9 using Google Dialogflow:

Or if people think there is a better approach.

Thank you,

Izzy
