Only get the 20 first documents of my Firestore Database REST API

Hello guys,

I have a collection of 400 documents in my Firestore Database and I followed the documentation tutorial for setting up my AppGyver Data Configurator, but I’m just getting the 20 first documents of my collection.

Maybe it’s related to that, but, first, I had an error when running my test, so I modified my rules to that:
rules_version = ‘2’;
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow write: if request.auth != null; //need to be authenticated to write (or use “if false”)
allow read: if true;
}
}
}
