Agent Assist not showing for non-admins

We're toying with Agent Workspace on our PoC instance and can't get Agent Assist to show for users who aren't admins but have it itil role.  I've set it up on my personal dev instance and it works fine for non-admins who have the itil role.  

The non-admins can access Agent Workspace fine.  Agent Assist just doesn't show for them.  I don't see any type of acl that controls who can view it.   Thoughts on where to look?

Thanks
