In your question it contain only for bot storage document but you need to maintain bot state for each conversation. So if you want to store the bot conversation then you need to implement state management in bot flow.

The state and storage features of the Bot Framework SDK allow you to add state to your bot. Bots use state management and storage objects to manage and persist state. The state manager provides an abstraction layer that lets you access state properties using property accessors, independent of the type of underlying storage.

User state is available in any turn that the bot is conversing with that user on that channel, regardless of the conversation.

Conversation state is available in any turn in a specific conversation, regardless of user (i.e. group conversations)

If you want, you can additionally store conversation flow in Application insight as a custom event using TelemetryClient like trace,metrics,etc.
