How can I retrieve the document ID after inserting into the Supabase Vector Store?

When you insert documents using the Supabase Vector Store via the LangChain integration, the insertion method returns an array of unique identifiers—one for each inserted document. For example:

PYTHONCopied
inserted_ids = store.add_documents(docs)
print(inserted_ids)  # This prints the generated IDs for your documents.

Each element in the returned array corresponds to the ID generated for a document during the insert. You can then use these IDs to reference or update your documents later.
