Sending a command is the correct approach when you want to issue instructions or specific requests to a device, such as requesting a reboot. In the Azure IoT framework, commands are used for remote operations that can trigger specific actions on the connected devices.

Using commands allows you to perform various operations on the device without needing to alter its properties or request its details.

Thus, sending a command is the most appropriate and direct method to request the desired operation.
