Groups for local users pgadmin4

I have a containerized setup of pgAdmin4 V8.5 in server mode running.

Could you please tell if exists any plans to add functionality in pgadmin4 to create groups for local users in pgadmin4 in web server mode and set privileges for them?

Basic idea

To have one user with administrative privileges and who would have a list of databases (by server.json and .pgpass files) and give access by sharing database to individual groups or users.
For example pgadmin4 has 3 users:

- user admin@example.com has a list of 3 Postgresql databases (DB1, DB2 and DB3) and is in the admins group

- user user1@example.com is in the readers group

- user user2@example.com, is in the writers group

User admin@example.com shares DB1 only to the readers group and DB2 only to the writers group.

Users user1@example.com and user2@example.com avoid having to manually configure database connections when authorizing in pgadmin4 and get the list of databases from user admin@example.com.

The scheme in attachment.

Maybe you know any forks pgadmin4 or any another your projects which supports this idea I'd appreciate the information!

Thanks in advance!
