Option 2 is to use the Webhook channel, however this requires some custom implementation. In this case you could host a proxy service that feeds messages from the different channels to Chatlayer.ai. In this proxy service you can decide per incoming message at which bot you want to ask for an answer. Option 2 is a more advanced use case, and therefore not very common, but there are some bots within our platform that work this way. There is currently no out of the box solution that allows cross-channel switching between bots.
