there is not much else to it

so as mentioned on the goldfarb's link
- put a code in there that you want to be executed when the action button is clicked
- use kwargs dictionary variable to access some intrinsic data (node, parmtuple, …)

so overall it's similar to setting up a parameter callback for a button

What confuse me is why this is the action button section is to accessible (empty) with a button parameter?

Only in with an event. I tried to build one but for now im failing

Edit i found some answer but so far i didn't found great use of the action button feature compare to a simple button with a callback.

Until the moment when i decided to boost the default Sidefx "Null" with a bunch of additional features. It's not an HDA so there is no script module attached and if you could execute a bunch of python instructions in a single line format, it's rather limited!

But with action button , you could run a full standard python script that way !

Very handy... i don't think people know this so i thought was worth sharing
