Security in firebase/firestore

In a project I'm currently working on I'm using cloud FireStore and underlying DB.

I need my client (iOS and Android) to be able to read (no wrtie access at all) documents from cloud FireStore regardless of the user is logged in or not (actually not going to use firebase auth at all).

I do not want anyone to be able to access the data from outside the apps (thru the REST endpoints for example). I guess what I need is to bake in some sort of API-key into the app that grants the access, but I do not see how I can do this, can anyone guide me in the right direction?

I know you say you don't want to use Firebase Auth, but I think signing in anonymously is the way to go. This will allow them to receive a uid without signing up/logging in so you can validate them in your Firebase/Firestore security rules. The web version looks something like this, but its implemented for Android/IOS as well. This code is taken directly from here.

firebase.auth().signInAnonymously().catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.
    var isAnonymous = user.isAnonymous;
    var uid = user.uid;
    // ...
  } else {
    // User is signed out.
    // ...
  }
  // ...
});

IOS version
Android version
