Universal Links are a feature that allows users to open an app directly from a web link, rather than having to manually search for and launch it. This can be particularly useful in applications such as video calls or livestreams where sharing links is common. Setting up universal links involves creating a JSON file on Android and an apple-app-site-association file on iOS, which establish trust between the URL and the app. The process also requires adding intent filters to the AndroidManifest.xml for Android and enabling Associated Domains capability in Xcode for iOS. With these steps completed, users can share meeting URLs directly from their video chat applications without needing to enter channel names manually.
