One animation for many similar objects in unity?

Question

Unity

How to make one animation for many objects of the same type (ui buttons and ui panels). I want to make, for example, an animation of the appearance, but why, when I try to add the created animationclip for one object to the Animator component of another component, I can’t play the animation on the new component. Create the same animation for everyone? create a parent, record the necessary animations for it, attach an object to it, play it, detach it ? is there an easier option?
