Cant find folder on Hierarchy

Hi, im a noob in unity I am just trying to change the texture of some buttons.
The thing is, I can see the folder and buttons I need to change while I am in play mode but I cant see them if Im in stop mode.
Anhyone?
Thank you

Please look at the link in my signature, it’s hard for me to know what you’re talking about with that description.

What “folder and buttons” are you talking about? Perhaps you can take a screenshot and describe what “folder and buttons” you’re talking about? You could even circle them in Snipping Tool or Paint.
