last question, in my services architecture, I have some "admin" service that should directly read/edit some of the users stored in supertokens, in batch, without having any user logged in. For example they can read user details, update roles, add new users, etc... To do this, they should directly call the core instance? Or should I develop a dedicated set of apis in my backend? The second option sound strange to me because I would implement a sort of proxy to the core...
