How to fade music by event dispatcher? - widget to level BP

Hello,

I´ve made a widget menu that is created in level BP. In that level BP, i start the event with spawning sound so when the game goes to the widget, the sound keeps playing.

In that widget, i´ve made a button that starts the game that also have an event dispatcher to fade the music in the level BP, but the way i´ve setup it does not work. May i be assisted in this issue,please?

Edit: Basicaly, the sound would fade out right after the “On click Play Button” is pressed, instead, it only keeps playing without the fade effect.

LEVEL BP:
