Multiple database under app

Dear Angularfire!
I would like to ask if the application described below can be solved in any way.

So, I currently have 2 source codes with 2 firebase projects. Separate users and data for each project.
Thanks to a development, we are trying to unify the systems within the company.

**Consequently, the aim would be to:**

- `Application number one: We would not reach for this. Here will be the users and user permissions. for example: user.claims = 1 (admin)`
- `Delete users from the other application and set up the application 1 database. Only the admin can access this page.`
- `Application 1 would work in Firestore 1 and Application 2 would work in Firestore 2.`
- So far, I find this feasible.
- `How can I make sure in database 2 (firestore) to make sure the user has the right claims? Is it possible to move between projects in this way?`

Sorry if I'm not understandable, writing English is not my strength. If anything is not clear I will try to explain better.

**post: Most of Database 2 is completely public, unlike Database 1, which can only be viewed by a logged in user.**


Le rapport ne mentionne aucun fichier du dépôt, test ou point d’entrée. Commencez par examiner la configuration d’AngularFire et la prise en charge par Firebase de authentication/claims pour plusieurs projets ; le travail serait terminé lorsqu’une approche prise en charge ou une limitation clairement définie existerait.
