Color me surprised. But if you run the app using the sandboxing feature that it provides surely it will only be able to see other apps installed within that same sandbox?
What is "the sandboxing feature" you're talking about? The standard app sandbox built into android allows apps to discover each other for various purposes, and grapheneos doesn't do anything to attempt to plug this.
