iOS: how to customize your App icon?

The finished command can be downloaded from the iCloud link, and the icon file from the Telegram channel.

Step-by-step instructions:

1. Download the "Shortcuts" app from Apple.
2. Create a command.
3. Add the "Open" action, select the desired application. In our case, the Genshin Impact video game (requires download).
4. Select "Share" in the toolbar, "Add to Home Screen", upload your own photo as an icon.
   4.1. If you can't write for the icon before adding the shortcut, you need to rename the command itself.

Profit! You are excellent!
