So I dragged a Container from Base Templates

But I have no idea what the following attributes mean, or how to assign specific treasure to the chest.

Activation Group ID
Activation Treasure Level
Active Level Override

What is Treasure, and Treasure Level?

There is a number in [] , what's that for?
