How to purchase laser pointer

I downloaded the free version 3 but can’t find an option to purchase the laser pointer. There is an option to purchase the customer screen and a useless link to gift the free app. Is it missing or am I just inept?

If you had PhotoPresenter previous to V3 you have it unlocked automatically. To unlock the Laserpointer tap an image. The “eye” icon will turn into a Laser Pointer Icon. If you tap the laser pointer inside the photo thumbnail.
