workflow document approval state only available to specific users - how?

Question

How do you set a document to change to approved state after approval by a specific user? In the access control of a folder, I see a work-flow access column - looks like anyone who has ability to change Workflow can set the State to Approved. 
 Thx, Regards, 
 Kevin.

Found it ... thx to Bentley support... PW Administrator > Data-source > Workflows > select the Approved State in the Workflow > Properties > Document Security ... Add only group or users that can approve and enable change state permission
