@Generated public final class Message extends com.google.protobuf.GeneratedMessage implements MessageOrBuilder
 `Message` is one unit of communication between client and server. It can be
 associated with a context and/or a task. For server messages, `context_id` must
 be provided, and `task_id` only if a task was created. For client messages, both
 fields are optional, with the caveat that if both are provided, they have to
 match (the `context_id` has to be the one that is set on the task). If only
 `task_id` is provided, the server will infer `context_id` from it.
Protobuf type lf.a2a.v1.Message
