Where can I find the hook name of ps_featuredproducts?

[Deminer84]

Good morning everybody,

could you tell me please where can I find - or just what is - the hook name of module ps_featuredproducts?

I hope it is the proper one.
I want to add a list of random products in 404 page, under the notifications of the "not found" page.
It will show some products, that customer might be interested in.

This is why I think featured products can work well here, or should I do it in another way? 

 

Regards,
Tom.
