Is it possible to get the number of connections from a rclpy.Subscription object? (In ROS1 we had "subscriber.get_num_connections()")

If it is not possible, what is the alternative?

This is providing the number of subscriptions for a rclpy.publisher.Publisher and not the number of publishers for a rclpy.subscription.Subscription.
