Currently I am using aws-iot-device-sdk-js to create mqtt connection. For that this library provides a class Device and interface DeviceOptions to pass the region, hostname, certPath etc. to create a connection. But on the new library aws-iot-device-sdk-js-v2 I didn´t find any class or interfaces like Device or DeviceOptions to pass the params. What is the equivalent class and interfaces for that? Or is their any migration guide to migrate aws-iot-device-sdk-js to aws-iot-device-sdk-js-v2?

Thank you
