How to reference a widget component's class and play an animation without having to construct an instance

Hello! so i have a interaction prompt blueprint that contains a fadein custom event aswell as the animation

i had it already working where every time the player looks at an interactable object, the interaction prompt of that object will become visible and vice versa

now im having difficulties adding an fade in and a fade out to this system.


the problem is that i must have a reference for the actual interaction prompt Widget, where in many tutorials with ui animation they would simply construct the widget, in my case it seems that the widget is already instanced if that makes sense,
the target needs a reference to InteractionPromptW im not sure how i can reference it.

sorry i have pretty much no idea what im doing, any help would be much appreciated thanks!
