	 * Execute a request with a single response such as a "query" or "mutation".
	 * @param request the request to execute
	 * @return a {@code Mono} with the {@code GraphQlResponse} for the response.
	 * The {@code Mono} may end wth an error due to transport or other issues
	 * such as failures to encode the request or decode the response.

	 * Execute a "subscription" request with a stream of responses.
	 * @param request the request to execute
	 * @return a {@code Flux} of {@code GraphQlResponse} responses.
	 * The {@code Flux} may terminate as follows:
	 * <ul>
	 * <li>Completes if the subscription completes before the connection is closed.
	 * <li>{@link SubscriptionErrorException} if the subscription ends with an error.
	 * <li>{@link WebSocketDisconnectedException} if the connection is closed or
	 * lost before the stream terminates.
	 * <li>Exception for connection and GraphQL session initialization issues.
	 * </ul>
	 * <p>The {@code Flux} may be cancelled to notify the server to end the
	 * subscription stream.

	 * Factory method to create {@link GraphQlResponse} from a GraphQL response
	 * map for use in transport implementations.
