Loading multiple bots on single facebook page based on the language users are using for query

My Scenario:

I have two different rasa models i.e. in English and Nepali. Now, I want to integrate it into Facebook messenger such that if the user’s query is in English then the response should be made by our English model, and if the query is in Nepali then the response should be from the Nepali model.

As for tutorials, blogs, and documentation I am only able to link a single bot to Facebook messenger. Does anyone have an idea on how can we integrate a bot into Facebook as the scenario mentioned above? Thank you.
