API to set Read File Contents (workflow permission) for specific user.

I am trying to develop a method in vb.net of setting the workflow state permission "Read File Contents" on for every state in our vault for a specific user. I have already given that user "Read File Contents" permission for every folder in the vault, but without the matching State permission the files are still hidden. I have the user's ID and state.ID for every state but I'm failing to find the equivalent of IEdmState6.UserPermission, IEdmUser9.StatePermission or edmStatePermission. Any suggestions are greatly appreciated

For anyone interested I included the code to list all workflows and their included state names.

    Private Sub WorkflowNames(ByVal Vault As IEdmVault7)
        Dim WorkFlowMgr As IEdmWorkflowMgr6
        Dim WorkFlow As IEdmWorkflow6
        Dim state As IEdmState6
        Dim pos As IEdmPos5
        Dim pos2 As IEdmPos5

        WorkFlowMgr = Vault
        pos = WorkFlowMgr.GetFirstWorkflowPosition

        While Not pos.IsNull
            WorkFlow = WorkFlowMgr.GetNextWorkflow(pos)
            Debug.Print(WorkFlow.Name)
            pos2 = WorkFlow.GetFirstStatePosition
            While Not pos2.IsNull
                state = WorkFlow.GetNextState(pos2)
                Debug.Print("->" & state.Name & ", ID:" & state.ID)
            End While
        End While
    End Sub

The output looks like this:
