Clarification needed on the installation of the heat sink sheet that came with the CM4 adapter

This seems to be the same “graphene” heat sink sheet that was available as an upgrade for the A-06, I believe.
How do I use this with the CM4? Which side towards the SoC, which side towards the shell? Is one of the sides supposed to be sticky? The pictogram that came in the package seems to suggest the sheet should stick to the bottom shell?
And how am I supposed to use the thermal pads that came with it?

From this post DIY a Graphene Cooling System for DevTerm looks like one side is sticky.
