1) In Device management > Chrome > Android application settings, turn on Enable Android applications for your domain
2) In Device management > Chrome > User Settings > Android applications, set Android applications on Chrome Devices to Allow, and choose your preferred setting for File System Migration and Access to Android applications
3) In Device management > Chrome > App Management, add Makers Empire 3D as an Approved app by selecting Android Apps in App Type and pressing the plus button in the bottom right and searching for Makers Empire
4) After approving the app, press on it in the list to configure the settings. If you turn on Force installation and Pin to taskbar, Makers Empire 3D will automatically appear on the bottom bar of the Chromebook screen when logged in.
