Retrieve subcollections from firebase wrapper

[Weulass]

Is there any way to retrieve all documents associated with a subcollection presents in a collection using the firebase wrapper ?
I tried without success:
server firebase_server
options (
object 'firestore/users/details' -- format: 'firestore/[collection_id]'
);

In this case, details would be a subcollection in users collection
Thanks in advance

This is not currently possible because the regex in the code matches only firestore/collection format while building the API url. But we should be able to update to allow subcollections in the regex. WDYT @burmecia?
