dialogflow CX create agent dont have API to add datastore or knowledge base

[chodankarcc]

Hello,

We are exploring Gen App Builder APIs for Conversational AI, I see for that we can use combination of Dialogflow CX and Discovery Engine APIs.
We want to create datastore or knowledge base while we create an agent in Dialogflow CX. We checked file from dialogflow-cx/create_agent.py or its library but we don't see any mechanism to create this. We also couldn't find creating new datastore for existing Dialogflow agent.

Can you please let us know if there is any API or programmatic method available to do so?

Thanks,
CC
