Connecting supabase vector store documents to another table with foreign key

I’m building a workflow that pushes rfp text to a supabase vector store, with the default pgvector setup. That is working as expected. However I have another database called client that I’d like to have associated with each row (chunk) created. I see how I can add a foreign key to connect the documents db to the clients db, but I don’t see a way to assign the client id when passing the content to supabase using the supabase vectore store node. Any ideas on how I’d do that?

Thank you!
