By default, this block is visible to all logged-in users (including students, trainers, and administrators), as long as it is added to a page they have access to. The users shown in the list depend on the viewer’s permissions, so individuals will only see other users they are allowed to view within that course or context.
This block is set up using LMS' default configuration. If you would like to make any changes—such as restricting visibility to specific roles or modifying how the block behaves—please contact our Support Team with your requirements, and we will assist accordingly.
