Hi Team,
We have created a Custom AI Agent in Elasticsearch and are planning to access it from an external application through the A2A (Agent-to-Agent) Server.
Currently, we understand that authentication to the A2A Server/API can be done using Basic Authentication with an API Key.
We would like to understand whether it is possible to use any alternative authentication mechanism instead of Basic Auth/API Key when connecting to our Custom AI Agent externally through the A2A Server as in our prod env basic auth will not be accepted as per security concerns.
