Current ingame trend showing users available options umg

Hi,
So currently there has been a trend where a player is shown a little popup ingame showing the available options that user can choose from. Like for example pickup or break an object and open/close are door.
i have an idea how to do this but im not exactly sure, and i dont want to end up doing something that was a huge waste of time so was hoping if someone could confirm my method would work.

First make a umg widget that shows the options open/ close a door for example using a trigger box. then link that to an event hit on the doors collision to enable visibility of umg widget. then capture an input interaction event, which would be the F key input event. and play a timeline animation. also can i control the umg to be placed above the handle

I have the timeline animation working but im not sure how i would limit the scope of the input event. for example say i collide with the door and see the options. if i press F how will i make sure it only applies to that blueprint and not any others. not any other door in this context.

Thanks for your time
