How do i make a tool not be in the hotbar?

i have a punching tool (lol i still need to make animations for it) and i want to know how to make it not be in the hot bar and just have to game UI tell you what button to press, I don't know how to do this and i would appreciate help.

There would be two ways of doing this (I think):

You hide the CoreGui for the backpack or you could create a Full-screen (if u want to) TextButton for it.

Most games that operate like that but still have the Backpack available in CoreGUI often do not follow the sample principals as you are, instead of using tools they create their own various systems, including inventory ones, etc. Hope you understand this.
