Tie membership and appointment plus together

Dear support, I'm a bit of a novice with wordpress so I'm a bit confused exactly how I tie the membership registration/login plugin in with the appointment plus plugin.

I have watched and followed your video tutorials for both the plugins and configured everything I believe is needed including staff, services, schedules etc.

What I want to do is allow new visitors to my site to be able to register and login with password authentication in order to book an appointment. I do not want the customer to be able to book an appointment without first registering, If that makes sense?

I'm also not entirely sure what pages or exact widgets need to be enabled for the login/registration process to be shown on the main page menu or sidebar.

Any help or pointers will be gladly appreciated.
