If your app is only released on Google Play but is not released on AppGallery, you need to complete the following configuration and submit a monetization application for your app. Your app can start traffic monetization only after the application is approved: https://developer.huawei.com/consumer/en/doc/distribution/monetize/addmedia-gp-0000001149967192
