Configure: Hook

Hi, first of all, greetings, I am a new player maps kz.

I recently learned that the hook command can be used when the map is completed, the problem is that I and my players can use server unfinished map, and I want to know how to do so you can use when you finish the map and receive a reward for the same.

Greetings and apologies for any inconvenience and my bad English (I speak Spanish)
