Should I use rails admin for end user?

I'm building an API management apps where every user able to find their own token for making an API request. Every end user will have to manage their own API access, they should also have access to many other custom endpoint.

At the moment, the Rails Admin is being used for the internal administration. Such as CRUD of "AdminUser", "Payment", and other internal system management.

The question is: Should I use Rails Admin's feature for this functionality (as in exposing admin control to every regular user)? Or should I just create a separate admin section for the general user with a standard form?

I'm not very experienced in Rails Admin implementation. So, I wonder if I should use it for too for the end user.

Thanks for your time & help!

Update

Some of my basic concern about using Rails Admin to me is that: Rails Admin is for developer or internal adminstration. Aside from that there will be some risk of giving a wrong permission to the end user.
