How do you instantiate UI elements in unreal engine?

Hey there, I’ve started to use Unreal Engine more often after using Unity for a while. I need a character select system where the character buttons show up if you own the character, otherwise they don’t. This is similar to the fortnite locker, where skins don’t show up until you have them. I know in Unity, you can just instantiate UI elements to the screen, while in Unreal, I’m still not sure. Any help?
