Is it required HCM subscription to utilize "Position Hierarchy" functionality in approval workflow? 

I know the following Doc. But it is not clearly described about it.

So, can we use "Position Hierarchy" functionality without HCM subscription?

Minimum HCM Setup Required For Non-HCM Implementation And Procurement (Doc ID 1947052.1)

If it is allowed to utilize "Position Hierarchy" functionality without HCM subscription,

are there any latest how-to doc for setup the custom roles?

Because Doc ID 1947052.1 is showing old UI.
