How to use Vector DB Reader and Vector DB Writer in AI Agent Studio

As part of an Enhancement, we have chunked and embedded the Access DB data and stored it in a Vector Database.

As per the 25D patch we have a new feature Vector DB Reader. I attended the 25D session last week but there was no information on how to use this Vector DB Reader feature. I Couldn't even find any documentation or recording on how to use these new features available in the 25D patch as part of the AI Agent Studio.

From my understanding, the Vector DB Reader should be able to directly read data from the database by simply providing the Index Name. Could you please confirm if that’s correct? Additionally, does the Vector DB Reader automatically convert the user’s query or prompt into vector form before performing the similarity search, or is that something we need to handle explicitly in our implementation?
