  body: any,
): void

	Type	Description
`fromClientId`	`Id`	The `Id` of the other client (in other words, the other system) that sent the message.
`requestId`	`IdOrNull`	The optional `Id` of the message, which should be returned in the response (if requested) to constitute a matched request/response transaction.
`message`	`Message`	A number that indicates the type of the message, according to the `Message` enum.
`body`	`any`	A message-specific payload.
