How do I project file icon

Hello when i look under the project files to the right when im inside the game engine and i look under the icons tab under project files how do i know which photo changes what icon . all i see is that it says icon.png but it doesnt it really says what image are u changing such as am i changing the desktop version of the icon or the mobile icon etc Does anyone know which icon is for what ?

I would just change the entire set, I am in the habit of making icons from 16 ox all the way up to 512 now. Different app stores and game sites require different sizes.

Okay thanks I guess that makes sense to do. Hopefully I can buy a c2 license soon so I can put it on the app store

It is absolutely worth every penny.

Yeah the whole last month I been thinking do I want to buy a gamemaker license or a C2 license and then today I was like the winner is C2 lol but thanks for letting me know its worth it
