Restrict the visibility of Schemas to non-Admin users

Hi All

I  need to create schemas for a new project for the Education Department in Adobe Campaign . I have a requirement, wherein Education Department users should not be able see schemas of other departments (such as finance department, health department etc) inside workflow activities as well (for eg. while browsing schemas inside query activity of workflow). All of the Education Department users will be non-Admin users.

Could you please help me, how can i restrict users so they will not be able to see other departments' schemas.
