How can I make a long press of a key in Unity to perform some action?

Question

Unity

I have a script for buttons, in this script there should be a function PressButton (Action CallBack), which will be called in another script through a button: BtnE.PressButton(). PressButton should return CallBack when pressed, maybe I don't know CallBack.

For example, we do it tritely in the update through if getkey in it, we make a certain timer that keeps the timer ++ button for as long as it is and when a certain value is reached, we send a callback or do something there.
