Problem about The Communitree

I have the problem about the Communitree, and here it is…

After unlocking “The Candy Tree” and progressing a little bit, you will see a button that says throw 10 candies on the ground, but if I click it, it will say no to me. Here is the image.

In my opinion, there’s should be something that if you click on the clickable, you will lose 10 candies, but you’ll attract children, which MULTIPLIES candy gain by a certain amount. (Base is (1.25^Children+1)x). However, the effect disintergrates every second until the effect is at x1 and lasts for 10 seconds. Upgrades, or content will boost a number amount of candy thrown, boosting effect and making it last long, or add more content related to throwing these candies on the ground.
