Module access not available in v11

I want to remove some modules for the user, for that i opened respective user form but no module access option available there as it is in v10. Im using v11. Below role access there is toggle of ‘allow desktop icons’ but its also not working. Disabled modules from ‘allow desktop icons’ are visible at user login.

Please Help

You can do this via role permission manager. If a user does not have any rights to all the DocTypes of a certain module, the module will not be visible to the user. At the moment there is no provision to add module level restrictions.

and what about that ‘allow desktop icons’ ; that also not working
