Realization between interfaces

Hello,

For some modelling needs, I would like to create realization between interfaces (e.g. between logical and physical, or between 2 physical)

I’ve seen on the expert mode that such attribute exists on interface definition:

But I don’t know how to fill these attributes? Or in any case the modelling action that allow to complete these attributes?

How to define these realization link between interfaces?
