varying sound in interaction blueprint door/drawers

[Smina]

Hello,
following this video:

I made a Blueprint that I can pull into the level and then add doors or drawers that can be opened using linetrace.
Unfortunately I searched several videos and tutorials but none of them mentions how to apply the sound of the drawer or door to it.
Might be something totally easy, but I really am having difficulties finding out. Where and how would I add it in the blueprint?
If someone could explain it would be nice.
Greetings
