This script enables deep linking for Android emulators and real devices as well as iOS simulators and real devices. It uses the `mobile:deepLink` command in Appium to open a URL on the device, which can be used to trigger deep links. The script also covers the challenges of using Siri on iOS devices and provides a solution for launching Safari and entering the deep link URL. For cross-platform compatibility, a helper method is created that can be used to open deep links on both Android and iOS devices.
