As a WebApp Admin, you have the possibility to assign/ restrict users' access to different dashboards based on their roles.
In an organization, we have hierarchies and each role/level should only be able to view/access certain reports. This is also possible on WebApp through the below procedure;
Define user roles on the Client settings page.
Once user roles have been defined, click on the dashboard you what to assign WebApp users and scroll to the attach roles section.
Click on the + icon at the far end of attached roles space then select the roles you what to attach to this report then save.
