See the documentation for this widget.
Step 7 from section 'Implementation', the microflow fetching the step list should set the normal, active and visited steps with respect to the current situation, ie: once you are in step 2, step 1 should have the visited status, the current step 2 should have the active status and any next steps should have the normal status. Use a loop inside the microflow to walk over the wizard steps.
Let me know if this helped you.
