I have users who sign up through mobile front and need to go through approval flow to approve them before they can use the app (sign in) the backend is developed over ruby on rails/ db postgres
Currently there is an admin panel developed on same BE server but very basic and not providing proper CRM/ approval functionality with limitations to add new features related to user approval and CRM functionality. Number of contacts could reach 100 K.
Solution will have two way integration with back end.it will receive information about new sign-up users, operators will approve / reject then will send the decision back to the Backend server. it will also manage all app users who has already been approved. I wonder of there is a similar ready solution or I should make effort and build one to suit my needs.
Appreciate if any one can guide on the best scenario here.
