- Open Apple Configurator 2 and plug in your iPhone or iPad
- Click Add, login to the App Store and select the application you want to install
- Open up ~/Library/Group\ Containers/K36BKF7T3D.group.com.apple.configurator/Library/Caches/Assetsand wait until theTemporaryItemsdirectory appears
- Copy the application from the newly created temporary directory, but do note that it will disappear once Apple Configurator is done installing
- Double click the .ipaon your Apple Silicon (M1) device and install it
- Fix permissions on the installed application by running sudo xattr -rd com.apple.quarantine /Applications/<your_app>.app(if you skip this step, you're unable to start the application)
Note that it's easier if you already have the application installed, as Apple Configurator will prompt you about overwriting the existing installation, at which point the temporary file (the .ipa) will still exist, until you choose an action in the prompt.
