Is there a web interface for managing users and tablespaces in oracle 19c

I just installed Oracle 19c on Red Hat and would like a graphical way of managing users and tablespaces. I enabled EM Express but the new interface (omx) does not allow to manage users, and the old (emx) interface cannot be used because Flash is forbidden by our policy. I also discarded SQL Developer since it is too complex: I would like a simpler tool. Does oracle database include anything similar to the EM Database Control of oracle 10g?
