How can I limit visibility to a list?

Only System Administrators and Lists Managers can limit the visibility to a list. List Administrators can limit the visibility of any list to which they have been assigned. To limit the visibility of a list, go to the left sidebar and click on the “Collaboration” button > "Lists" >  select the relevant list > "About" > go to "Audience". The Audience picker tool allows you to select the audience that has permission to view the list. You can configure the audience so that the list is visible to everyone or to a limited audience. For a limited audience, check the “Limited” option, select your criteria by clicking on the “+” button, and then click on the "Save" button. You can select one or several entities and limit the audience even further, e.g. to specific departments, teams, job titles, contract types, etc. There is also an option to explicitly include or exclude employees. You can preview the employees included in the audience by clicking on the “Preview” button. If needed, you can remove employees by clicking on the “X” button above their photo.
