How to seed active Order/Invoice Number from a Fusion page into an AI Agent Studio agent?

Summary:

Passing Fusion page context to an AI agent — so it "knows" the active Order/Invoice before any tool call

I'm building an embedded AI agent (Oracle AI Agent Studio / Digital Assistant) inside Oracle Fusion - Supervisor or workflow Agent . The goal: when a user is on an Order page (or AP Invoice page), I want the agent to already be aware of the current Order Number / Invoice Number from the page context — before it calls any BO or REST tool.

In other words, instead of the user typing "tell me about order 12345," the agent should know they're working on order 12345 the moment the chat opens, because that's the record on screen. The tool/BO call would then use that context, not derive it from user input.
