You can install and upgrade apps on cloud phones in two ways: individually or in batches.
Open the cloud phone, tap the app icon in the bottom right, search for the app you want, and install it. This only affects the current cloud phone.

Sign in to your Google account and download the app from Google Play.
Upload an APK file to the cloud phone and install it.

Find the app in GeeLark’s App Store, choose a version, and install it to a specific group. The app will automatically install on all cloud phones in that group when they start up.

Upload APK/XAPK files manually. After uploading, go to Team’s applications and turn on installation.

Open the cloud phone, tap "Application - Upgrade" in the bottom right to see installed apps and versions. Click the triangle next to the version number, select the new version, and tap "Upgrade."

Find the app in Google Play, download, and install the update.
Upload the new APK file and install it to update the app.
In the Team’s application, click "More" then "Update," choose the new version, and apply the update. The new version will install automatically when cloud phones start up.

For apps installed from uploaded files, delete the old version first, then upload and install the latest version.
