Get deviceModelId and deviceInstanceId [Optional]

If you are not an experienced developer or don’t need gactions implements, pass this section.

If you want not only pure Assistant embeding but also customized gactions for device, you might need to get deviceModelId and deviceInstanceId. To help understanding, deviceModel is something like Volkswagen Golf or MagicMirror and deviceInstance is something like mom's car or mirror in living room.

For deviceModelId

You can get deviceModelId as a result of previous register a device model step. In Device registration menu in Actions Console, you can find it.

For deviceInstanceId

You need additional google-assistant-sdk library. See Manually Register a Device with the REST API page.
