[Radxa X4] Attaching PoE Hat and Stock Cooler at the Same Time?

I found this thread, which is odd: X4 PoE Hat PLUS Heatsink possible?

It always about the PoE hat being compatible with “other boards,” but it’s sold as an X4 PoE hat.

At this point I’m also not clear if the kit I have actually has all the parts I need (that is, if it’s been updated per the previous thread).

@ryann , could you please provide an update from the last thread confirming what is needed to make the above kit work with the stock heatsink?
