PCH is referring to the chipset in common terms (Platform Controller Hub I believe). The chip that interfaces between the CPU and the rest of the general Motherboard. Some things, Like GPUs, and certain storage devices are connected directly to the CPU. Most other devices like USB, network, storage, etc are connected to the PCH.
Inside a laptop, anything below 90C is probably okay.
With a specific chipset name we could actually look up its maximum temperatures.
Picked a recent chipset at random, rated up to 110C. Typical CPU or GPU will start throttling well before that to keep temperatures down.
No, that is still fairly normal. The CPU and GPU will have the bulk of the cooling on them, the PCH is a very low output part, so it gets less attention.
On some systems the PCH isn't even cooled.

Anything below 90C is well within operating specifications. Under very heavy loads you can expect the CPU to possibly reach 90+. Gaming typically won't achieve that. RTX 2060 has a larger surface area, so usually will stay cooler at the top end.
What you are seeing as 66c and 65c is just telling you that the CPU and GPU share a heatsink, so will stay close to each other in temperature when one isn't disproportionately loaded.
As I suspected, PCH is not cooled:

It is the exposed chip below the left fan, to the right of the wifi module.
If there is room you could add a small heatsink, but it isn't necessary. They left it bare because it isn't going to overheat.
Yes, 79C is fine.

Update: after 1:30h of playing strandeed deep and 40min of warzone max temp for cpu was 68c for gpu 65c and for pch 75c
all good? no need to worry or?
I don't have the laptop in hand to tell you how much height is available inside once it is closed. You could add a thermal pad and try to connect it to whatever is above it, but that might not help all that much. If you wanted you could maybe get a copper shim, just a thin sheet of copper, and stick it on there, just make sure it doesn't short anything out. None of that is really necessary.
Your temperatures are fine.
60C is about perfect for an SSD. The flash is actually most efficient at room temperatures above ambient. The real producer of the heat is the storage control chip on there though, but 60C is perfectly fine for a chip.
