Did you use additional underlayment under Coretec Plus floorings ?

We are planning to install COREtec Plus XL on concrete floors. Besides using a 6 mil vapor barrier, will installing an additional underlayment provide better support against vertical denting and/or provide better heat insulation ? This is at ground level, i.e. underneath is the foundation.

We are also planning to install COREtec Plus XL Enhanced as floating floor on previously installed vinyl (glued) flooring in our basement. Anything to consider differently here ? Planning the 6 milm vapor barrier here anyway. Many thanks in advance for any pointers.
