How to make key play and stop sound?

within the level Blueprint i made it work, so that whatever key i press the Sound will be played. Here im using a “PlaySound2D”

Now i want to set up to stop it when i release the button.

Herefor i use “Stop” and connect it with “Release”… but here i get an error. i guess i need a target but how to get a target?

Im not able to drag and drop my SoundCue into the levelBlueprint to make use of it to “get audio component”…

What i need to do?
