Adding Custom Metadata to VectorStoreChatMemoryAdvisor

[KushParsaniya]

I am currently working with VectorStoreChatMemoryAdvisor. By default, it adds conversationId as metadata, but I want to include userId as additional metadata.

I have reviewed the source code and try to add userId in the advisorParams, but it appears there is no built-in support for adding custom metadata in VectorStoreChatMemoryAdvisor.

Is there any way to do this?
