How do I create a “secret” store for specific customers only?

I have a normal wordpress webpage. I want to implement a woocommerce store in it, but secretly. What I mean is that the general visitor doesn’t get the store access and it’s not visible on the website directly. But specific users should have a login and be able to access it through a separate link ( for eg. https://www.averynormalwebsite.com/secretstore) and I want the entire store area to be password protected. What is the best way to achieve this?

For eg. a school website where students can login and purchase school stuff, but a normal user doesn’t even know that exists because they can’t create account/login or see the links that lead to the store. The students can’t even create accounts themselves, it is assigned to them by the school itself.
