What is the corresponding REST API to read and update the twins of Azure IoT Edge modules? For IoT devices this API works. So far I only can see the twins in the portal and via the SDK.
For reading Module Twin, the format of REST API for is /twins/${deviceId}/modules/${moduleId}?api-version=${IoTHubApiVersion}. You could refer to the code in Azure IoT Toolkit extension for reference to learn how it reads Module Twin.
