Hiding menu options for particular user groups

Hello RT users,

I wanted to know if anybody had a working example or was already hiding RT
menu options from logged in users?

The first item I want to hide is the "Logout" button for all users. We're
using SSO so it's not required to be present.

The second item I would like to hide (for a specific user group) is the
RTIR menu option.

Any help or suggestions would be much appreciated,

Thank you!
