Help? - First Person camera, focus on an event/object on button press, how to?

Hi,

I’m wondering if anyone can help, i’m not too well versed at the moment using Blueprints so any help is greatly appreciated. My team and I are looking to implement a mechanic into our game similar to the one shown in the video below:
The Last of Us - L3

Description: When the player is supposed to focus on a particular object/area/event, the game will display a button hint; in this example: L3. When the button is pressed, the camera zooms into the event and holds for a time.

How is the best way to approach replicating a mechanic like this?

Thanks in advance!
