How to require pre-approval of new accounts

I am building a site for a large group, and want to be able approve new registrants before their are allowed to becomes active. I have searched the Q&A and cannot find a starting point.

I am new to Auth0 and node.js and would appreciate both a pointer to the documentation on how to do this, and some sample code I can build on.

The other option might be to disable self sign up and replace it with a request process.

You might also want to disable the verification mail in case of no verification required:
