Bricks for Burgers

I took my 2 kids to the game for the first time last night and it was an amazing experience. Couldn't have picked a better game to go to. At the end of the game, Sengun hit 2 critical free throws and then they missed 2 free throws. I saw the Whataburger thing appear on the screen, but in all the excitement I didn't pay attention. I assumed we would be able to use our tickets in some way to get the coupon later on.

Is there any way to get this coupon after the game?
