How to make a variable "public" and editable when the eye icon next to it does nothing when i'm clicking on it ?

Hi

Those are just in the widget itself in the designer menu when i add a button then i click on the top right side and check the “is varibale” on then on the graph itself this button shows up and is set as not public with eye icon closed. My friend tested this and his variables are by default all public with the eye icon open and i need to get mine as well like he has them. Or another example is from the tutorials that i am following on this is pretty much the same. In the tutorial as well all those variables are public and the eye icon is open on all of them. Btw check my other post about it there is more info with screenshots so you can see those examples what i just described there. Ty
