MDM Workflow - on Portal

Dear MDM fellows

Could you plase help me with I believe basic question. I need to set up some workflows on the portal.

What I had done is so fair is:

- prepare portal with pages and iviews

- workflows are defined in the repository

Now I would like to have a tab, to be able to start workflow from the portal (right now I can do it only in MDM Data Manager)

On the iView I have marked option: Is Workflow Enabled? to Yes, however I cannot see workflow tab in right top corner, there is only configured previously "My Bags".

How can I set up Workflow to on the portal, is any option in repository table I should mark, or anything else on the portal iViews details pane I have to mark or configure?

Thank you in advance.

BR
