When attacking with GiaF, is there a priority window between when Tyler plays an instant and when they choose whether to return GiaF? 6.6.6a seems like it says you have to choose whether to return it when that triggered layer gets put on the stack, and the layer gets added to the stack before the other player can respond to the instant that triggered it. Is this correct?

A trigger is put on top of the instant. And on resolution of that trigger you choose to bounce or not
