How to make a simple 'Hold Item' mechanic for First Person?

Hi all. New to unreal, using 5.0.3, and trying to make a simple mechanic for this and been trying for days!

  1. I want to see a hammer on the floor. The player (First person character with no arms, just a camera basically) overlaps with the hammer, clicks on it, and it destroys the hammer off the floor and just like attaches to the bottom right of the screen as if the player is now holding it.
  2. If they go to the correct Door, and Left Click, it sort of animates the hammer down into the door handle location, and then Destroys Hammer. But if they are not in the area of the door and Left Click, nothing happens.
  3. This mechanic is in LOADS of basic horror games. It’s just like a usuable object basically. That you hold. I am trying really hard and struggling.

TL;DR: I am trying to make an extremely basic bare bones ‘Pick up object’ mechanic which the player can use, to be able to pick up a hammer, go over to a door, Left Click and the hammer pulls a nail out of a door. But i am really struggling.
