Unfortunalety the new Huawei devices don´t have the license to use Google Play Store.
The government action prohibits all US companies, including Google, from collaborating with Huawei. This means that Google is prohibited from working with Huawei on new device models or providing Google's apps including Gmail, Maps, YouTube, the Play Store and others for preload or download on these devices.
Huawei has a own store which is called "Huawei App Gallery".
This store is not supported by Carly. Therefor you can´t use Carly right now on new Huawei devices!
