A team is building a prompt agent in Foundry Agent Service that must ground its answers in live public web results and return the bing_grounding tool's source citations for a compliance audit trail. The team has already provisioned and paid for a dedicated Grounding with Bing Search resource for this purpose. A developer holding only the Foundry User role on the project tries to add that resource as a project connection so the agent can reference it, but the Foundry portal blocks the action.
What should the team do to get the connection created and usable by the agent?
