Hello,
You can refer this documentation https://docs.mendix.com/refguide/mobile/using-mobile-capabilities/deep-links/
Hope it helps!
While it's a good starting point, I am specifically interested in understanding how to achieve the primary goal of deep links, which is to open specific pages inside the app.

When you register a deeplink with a native app, you basically provide an endpoint for an external system to call. Whatever logic happens when the url is called is up to you. It works just like calling a regular nanoflow, so you can model the deeplink nanoflow to show a specific page in your app based on the parameters included in the url.
