Instant Apps, just like App Clips, can be launched by one of the invocation methods - the most popular ones are deep links and QR codes. When an Instant App is launched like this - it receives a URL - just like in App Clip, we can pass some information to an app. Instant Apps are similar to standard Android Apps - basically linking works just like in standard Android applications - thanks to that we can use the Linking Module of React Native instead of creating a new one just like in the App Clip case.
To configure linking for Instant App, follow the 🤖 Create App Links for Instant Apps | Android Developers article.
Instant App can also be launched easily without a URL - e.g. thanks to the Try Now button available on the Play Store - make sure to also handle this case in your Instant App!
