Once you have connected a member to their profile (using this guide), they will be able to log in and gain access to their own member view/portal.
From here they will be able to access their invoices, update their contact details, interact with other members in your space, make reservations on your booking calendar, and more.
The best and easiest way to see how the member view will look to your members is to add yourself as a member (using this guide). Once you have done this, you will be able to toggle back and forth between both the admin and member views anytime you make changes, allowing you to see how it will look to your member.
