Need an user admin plug-in for angular app

I need to build an user management system, I have few tenants, each tenant will have a manager and users. Manager can manage users for his own tenant not others. Upon user crud the login for the user should work accordingly. I need an out of the box angular/ react plug-in that I can use it in my SPA. Is there any third party integration I can use. Right now i have an react and an angular app which needs this feature. Auth0 is the login mechanism for both of the apps
Any help is much appreciated!
