How to play matinee from interactive widget?

As the title says,I managed to create an interactive widget to for my game.I’d like to press a button for playing an animation(opening a door).The thing is,in most of the tutorials,the widget is created and added to the viewport.The animation plays using an event dispacher.But the coding is made in the level blueprint and I need to make it in the interactive widget bp.So,any suggestions?

Thanks :wink:
