Summary: How to restrict document access by legal employer in AI Agents

Content (please ensure you mask any confidential information): Hi All, we have created an AI Agent where we have uploaded policy documents. The tool type being used here is document. We have multiple legal entities and have different policies.

we want to ensure that agent can only access and answer questions based on the documents corresponding to its assigned legal entity

Could you please advise on the best and correct way to configure this restriction, so that an agent can identify which legal employer it belongs to and respond appropriately without referencing content from other documents meant for other legal entities.
