Acuity Scheduling - Multiple Users for Calendars?

Site URL: https://www.janiejennings.com/

So the lady I am helping has a Pilates studio, and we have one calendar for her. I know how to add multiple calendars and set availability, etc. for the new teachers however, what I can't figure out is how to allow the new teachers access to the calendars without giving them access to everything else. 

Acuity says to go under "Users" and add new users, but because this is Acuity through Squarespace I do not see that option anywhere. 

Any help would be SO appreciated. Thanks. 

@AGLange Did you ever figure this out? I have the same question. How to add multiple users to Acuity?
