It's so simple to use it. You can see the tutorial in the app for more details, but before you do that, make sure you have the Shortcuts app installed.
You will need to create a simple automation task, so when the phone is charging, you will ask to launch this app.
The great thing is that the app will automatically launch when the phone is charging, showing you the animation/theme that you've selected.
