Laying flooring over concrete

[StressedDIYer]

I have recently purchased a house with an old extension, leading up to the extension the floor is suspended and the back 2 metre of the house is concrete. The concrete seems dry with no signs of damp and previously they had T&G chipboard screwed directly to the the concrete with laminate on top.

I have been told this is not the correct way to do it and can trap damp under the T&G, I wanted to fit karndean or maybe engineered wood but was wondering how to do this on the concrete without causing issues with trapping damp etc?

my thoughts were paint the concrete with liquid dpm,
then latex,
then T&G chipboard screwed down
Then ply
Featehredge

Then floor
