How do I make a gamepass insert something physical?

So, I'm attempting to make a tycoon game and I've been trying for a couple of hours to try and make a button that you're able to step on, and it triggers a gamepass pop-up for you to buy it, and you're able to purchase the gamepass, but the dropper does not physically enter the game.

Now it wont register as a gamepass button, its registering as a regular tycoon button
