RAG agent capability removed from knime?

Knime recently deprecated a bunch of AI nodes, specifically related to creating RAG agentic systems, like the “Vector store to Tool” node that let the agent access vector stores as tools, and also removed the “tool concatenate” node, that allowed the the agent to access multiple vector stores. What is the new approach to giving agents access to vector stores in knime after 5.5?

Any help will be greatly appreciated. My original workflow was built based on: RAG Agent
