SDK deos not provide API to Invoke another agent

Describe the Problem

Within AgentGatewayClient, there is a method 'list_agent_cards', but does not have a 'call agent'. (similar to 'list_mcp_tool' and 'call_mcp_tool'). With AGW, to send message to a remote agent, a fragment needs to be fetched, exchange URL and token, many same patterns have to be implemented by agent app. Why not create an API to be shared?

Propose a Solution

Create a new method 'send_agent_message'. Refer to https://github.tools.sap/fin-trm-dispute-resolution-ag/dispute-resolution-ag/blob/main/app/services/common/a2a_destination.py
