How do I make button claim reward when reach the score?

please help me guys :")

I want to make a reward for my game, when the player reach the score 50000 then appear a button to claim a reward. The reward i want put in a coupon.

i really thank you who wants to help me.

ps :sorry for my bad english :).

you can place an object that would initially be invisible, and that when reaching 50000 it becomes visible, and that if it is visible and clicked on it will do the function you want

thank you for your reply :)
