im surprised that nobody asked about this. firebase already have this functionality whereby i could export existing firebase firestore and authenticated users to another project.

in mongodb realm, collection and functionality can be export and imported. but existing authenticated users are not able to move. or maybe im missing something. i find this a big bummer when duplicating project for staging or testing or even for another client. i dont wish to need to do custom authentication todo this, but i am on the way todo it.
