/// Get the current URLs that triggered the deep link. Use this on app load to check whether your app was started via a deep link.
///
/// ## Platform-specific:
///
/// - **Windows / Linux**: This function reads the command line arguments and checks if there's only one value, which must be an URL with scheme matching one of the configured values.
/// Note that you must manually check the arguments when registering deep link schemes dynamically with [`Self::register`].
/// Additionally, the deep link might have been provided as a CLI argument so you should check if its format matches what you expect.
