How to Hide (Not Disable) a Qlik Sense TAB

[qlikhill]

I have multiple users.  I would like to hide Tab (NOT DISABLE) based on their role. For example, One is Director, another is  Office Assistant. When user login into QLIK SENSE . The TAB will be visible/hide based on their role.  Looking forward for any suggestions.
