Note

This installation checks (when the application starts) if the AR Foundation components are in the scene. If not, they are automatically added to make it work with ARCore and ARKit. If you need to set a specific behaviour, you should add the components you need by yourself. For more information about AR Foundation components and installation, check this documentation.
